It seems that there are a lot of questions regarding the Cyrix 386 compatible 486DLC and 486DRU2.  My info comes directly from Cyrix's Fast Fax service: And also from installing one of these chips in an IBM Model 80.  The 486DLC is a 486 instruction set compatible CPU which fits into a 386DX socket (Pin Grid Array, or PGA).  The DLC currently is available in 3 speeds. the 25, the 33, and the 40.  They do not have a coprocessor on board, but any software query will return coproc as present.  I guess they emulate the coproc instructions.  Math functions are on the 386DX level without the actual coprocessor.  The internal cache on the 486DLC is 1K.  Cyrix literature claims a 85% hit rate.  My informal tests show that the cache accounts for a 10% performance boost when it is enabled by software.  Overall performance boost from a 386DX-25 to a 486DLC-25 is about 60%.  The benchmarks I used were NU SI and QAPlus Dhrystones and Whetstones.  The performance, with the cache enabled, is about on a par with my 386DX-40 with 256K external CPU cache, which is around the performance for a 486SX-25.  The computer runs noticebly faster, and DOS 6 with Dblspace is not complaining.  The company claims OS/2 compatibility, but I didn't test it.  The 486DRU2 is not a chip, as commonly thought.  The 486DRU2 is actually a small daughterboard slightly larger than the 386DX, which contains the logic to manage the clock doubler.  This board plugs into the 386DX PGA, and the 486DLC-33 or 40 plugs into this board.  I guess the board doubles the frequency apparent to the CPU, and insert wait states when  access to the rest of the system is required.  There are no info available from Cyrix there.  Anyway, the DRU2 is available for 386DX-16, and 386DX-20 only.  Double these clock rates, and you get the 32MHZ and the 40MHZ DLCs. If Cyrix is planning to do the same thing for the DRU2-50, then they need to put out the 50MHz DLC2 first...  I also tested a DLC33 motherboard, along with a Cyrix Coprocessor.  With 64K external cache, performance were about 30% faster than the 25, but still significantly (25%?) slower than an actual Intel 486DX.  IMHO, the DLC is a great, low price upgrade for people who can't afford, or can't install, a new motherboard.  It is definitely worth what I paid for it, but if you need 486DX-33 performance, the DLC33 won't cut it.  I'm not sure about the DLC-40, but I think even if it matches the performance, it won't beat it in any significant way.  The last time I posted info about the DLC, people sent quite a bit of mail, asking where I got it.  So here is where I got mine:  Treasure Chest peripherals, they advertise in the Computer Shopper. 1-800-677-9781 The 486DLC-25 kit was $179.00  But....  I liked the chip so much that I found the supplier, and became a dealer. If you are interested in the chip, e-mail me, and I can fax or mail you more info.   I'm well aware of the net's policy against commercial use, So I can;t post anymore info here.  However, if there are more questions regarding the 486DLC itself, I'll post what I can.  jamesc 909-396-0408

Just a quick THANKS to the many who explained the backing up of my masters.  Apparently they are NOT copy-protected; I just used a program that is unable to handle high-density (old shit).  I was surprised to hear that "NO programs on high-density disks have copy protection," which someone back there said.  Huh!  Learn something new every day!

Hi,  I've got a Victor PC/XT with a 20 MB harddisk in it. The controller is a Toshiba MFM controller, with an additional 9 pins connector.  There are 2 busses from my harddisk to this controller. One with 9 wires and another with 34 wires.  The controller has two connectors for a 9 wire-bus and one for a 34 wire bus.  Now I got a 20 MB harddisk from a friend of mine, and I wondered whether I can connect this second harddisk to the same controller (there is room for a 9 wire-bus, but not for the 34 wire bus)  How can I solve my problem, any suggestions?  If you need more info, mail me, please (luttik@fwi.uva.nl).

I have a 5FG and think it is great. I haven't seen the Nanao's so I can't compare, but the 5FG image is very sharp and the color contrast is *extremely* good. I've used other Trinitron monitors (e.g. a Sun SS2 color monitors, which is a 19" Trinitron), and think the 5FG is at least as good, perhaps brighter, and has *none* of these silly horizontal lines running across. 	BTW, I could be wrong, but I thought that the 5FGe is slower as well as missing ACCUCOLOR. It may not be able to handle 1280x1024 the way the 5FG can.
The subject says it all. I'm wondering if anyone on the net has had any experiences with Cornell Computer Systems of California. I was checking out their ad in Computer Shopper, and they seem to have a good balance between service, price, and hardware. The question is -- are they reliable?  E-mail responses would be appreciated.

Phone support is quick and competent from many mail order firms, but not so quick and not so competent from others (Gateway included).  But my experience with computer retailers (which is significant) has lead to the conclusion that sales personnel and retail-technical personnel are forbidden to actually learn about the products they sell.

But I don't care about those things.  I do, however, care about my computer - i.e. I demand features and performance, and I'll be damned if I'll pay some high-school drop out commission on an over-rated, over-priced system and in the process be subjected to his distorted B.S.

I am no expert on this.  But I am pretty sure there is no way to recover this.  IDE drive has mapping information written directly on drives.  When you  low level format it, the information itself is gone as well, I don't think you can get it back unless you send it back to Western Digital and ask them to refurbish it for you.

Some BIOSes do not automatically install  COM3 or COM4 in the port tables. Programs like most modem programs which  write directly to the port work fine but anything that uses a BIOS call  fails. Find a BBS or FTP site where you can get a copy of PORT FINDER. Put  "device=pf.sys" in your config.sys or run pf.com from your autoexec.bat.  This little program will locate all existing ports and make sure the BIOS  tables are updated. It works great. PF will also let you swap ports and  such also if that is of any value to you.
Due to some problems with my IDE drive, I LL formatted the Maxitor7213AT. Now it started to give me some errors in some applications. I was told Maxitor has a utility called IDE_INT in their BBS, anyone tried it? Can some one tell me what that BBS number is? Or better, can I find the file in some ftp site? Or perhaps someone can email it to me? Thanks.  Feng

I think the original respondent (Guy Dawson?) was refering to something much more elementary.  Every partition (whether it is the entire disk or not) has two FATs and an initial directory.  If you have a small disk (50 meg or less), I would recommend that it remain a single partition. Unless you have some other consideration.  If you have a large disk (greater than 200 meg), multiple partitions can make sense.
Anyone have any recommendations/warnings about the Texel 5024 CD-ROM drive or about any of its competitors? I'm looking for a CD-ROM drive for connection to a PAS-16 SCSI port.
Hi,  I'm looking to buy a 17" monitor soon, and it seems that I can't decide what monitor I should buy. I have a MAG 17S (this is a .25 dpi version and it using a TRINITON tube) and a NANAO 560i in mind.  Does anyone know of any specification or problems these monitor have?  Actually, any related opinions at buying a 17" monitor will be welcomed.    Thanks in advance,
Hi peeps,  Here's another of those "any ideas" type queries.  I've been given an oldish Phillips TeleVideo terminal type thingy, without a keyboard.  But no problem so far.  When I dismantled it, I discovered that it is really just a standard RGB monitor with built in modem/ROM software etc.  Phillips kindly labelled the circuit board with the RGB inputs, so I connected it up as a monitor and he presto it worked - sort of.  The problem is that I have no idea where to connect the Sync lines. The display rolls continuously, but does change modes (OK only to CGA - but useful for my laptop).  Any of you wonderful people any knowledge of Phillips monitors?  I've tried Phillips in the UK and a very helpful guy told me that he has had several enquiries of this sort, but Phillips Computer is now under the auspices of DEC (at least in the UK).  DEC said sorry Phillips don't make it any more. What is it anyway? A UK support dealer said "Circuit diagrams? Sync?"  So any ideas.  John.

It's 1024x768, up to 72hz at that res, and it got a good write-up for image quality in a recent (Feb.?) issue of PC Magazine.  As far as I know, very little fully matches a NEC in image quality (at least according to the mags -- I can't tell any difference between the two!), but I think NEC is low emissions on only one of the two types.  There's VLF (Very Low Frequency) and ELF (I think that's Extremely Low Frequency).  The MPR-II standards set strict limits on both. But many comapnies, NEC included according to one article I read (I get a bunch of mags so it's hard for me to remember which!), which claim "low emissions" but not specifically "MPR-II Compliant" or "MPR-II Certified" only control for one, usually VLF, and ignore the other. 	So, the NEC probably has higher overall image quality (I consis- tently hear it rated as the best or close to the best), but not as low emissions as the Hitachi.  I like my image quality, but for all I know you may be more discerning.  Good luck!  					- Mitch  					v063kcbp@ubvms.cc.buffalo.edu
Wondering if somebody could tell me if we can change the cluster size of my IDE drive.  Normally I can do it with Norton's Calibrat on MFM/RLL drives but dunno if I can on IDE too.
Newsgroups: comp.ibm.pc.hardware Subject: Logitech 2-button mouse pin-out & BIOS routine availability? Distribution: world Organization: Purdue University Engineering Computer Network  I have a Logitech 2S-2f (or 2f-2S) 2-button mouse that I want to interface to a serial port of a different (non-ibm-compatible) system. The mouse is XT/AT/PS2 compatible, with a DB25 connector.  I tried to reverse engineer the mouse, but it has a micro-controller inside it.  If I could get the DB25 pin-out, and perhaps a copy of the BIOS routines that support it, I could map all this into my target system?  Anyone know where I might get the pin-out or the BIOS routines? Are the routines published someplace convenient?  Thanks! Silvio
Experiences with Diamond Viper VLB video card  Several problems:  1) The ad specified 16.7 million colors at 640x480 resolution with 1MB    of VRAM, which is what I have. This color depth is NOT SUPPORTED    with video BIOS version 1.00 and drivers version 1.01. A max of 65K    colors are supported at 640x800 and 800x600 resolutions with 1MB    VRAM.  2) With the 65K color choice I notice two minor irritations:     a) Under NDW, when an entry in a list is highlighted (such as in an       Open menu) and then is deselected, a faint vertical line often       remains where the left edge of the highlighted rectangle used to       be.     b) With Word for Windows, when you use shading in a table, the       display shows the INVERSE of the shading; for example, if you       shade the cell as 10%, the display is 90% (the printout is OK).  3) The big killer bug is using the Borland C++ Integrated Development    Environment. The problem occurs when you click on the Turbo Debugger    icon (or use the Debugger option in the Run command), and the    debugger application goes to VGA character mode (as it is designed    to do). The screen goes haywire, and is largely unreadable. The    Turbo Debugger display is all garbled.     Through trial and error, I have found that when the disrupted screen    is displayed you should do [Alt-Spacebar] followed by the letter    "R". This instructs Turbo Debugger to refresh the screen, and it    does this satisfactorily. I wish I didn't have to do this.     The bug is more than with the Diamond drivers. The same disruptive    behavior happens with the standard VGA driver that comes with    Windows. There must be something in the video card that mishandles    the VGA mode.        The problem is not my monitor. The same bug shows up when I use    another monitor in place of my usual one.  I still like this video card, and am hoping its problems will be remedied (they do offer a 5 year warranty).

I just bought a new IDE hard drive for my system to go with the one I already had.  My problem is this.  My system only had a IDE cable for one drive, so I had to buy cable with two drive connectors on it, and consequently have to switch cables.  The problem is,  the new hard drive's manual refers to matching pin 1 on the cable with both pin 1 on the drive itself and pin 1 on the IDE card.  But for the life of me I cannot figure out how to tell which way to plug in the cable to align these.   Secondly, the cable has like a connector at two ends and one between them. I figure one end goes in the controler and then the other two go into the drives.  Does it matter which I plug into the "master" drive and which into the "Slave"?  any help appreciated.  thanks...

I originally posted a complaint about how noisy my PC was. I got several  useful suggestions, but 1 was the most seductive: run your PC in silence by  removing the fan altogether!  Two variables:  1) I always run my PC without the cover, and  2) I'd be willing to attach a CPU cooler if that would make a difference.  Should I try to run my PC without a fan? I know it sounds like utter folly so  I'm asking - has anyone done this succesfully? Or tragically? You're answer  may save my PC... Thanks.
