Interesting.  Would you care to explain to me then, how my SoundBlaster Pro card and my printer card are sharing IRQ 7 successfully?  I assure you that they are both set to IRQ 7 and that I have no problem.  My computer is a DTK 286-12 IBM clone.

Does anyone have enough experience to report whether disk data compression has any effect on the optimal disk sector interleave? Offhand, I expect that the time required to decompress disk data would increase the optimum disk sector interleave.                                               - Alan Hinds

I believe you are right.  Both SCSI and SCSI-2 support 8 devices on the bus (normally that would be the host controller and 7 targets) each of which may have up to 8 logical units (LUNs).
Wow, you guys are really going wild on this IDE vs. SCSI thing, and I think it's great!  However, I think that some people (such as myself) would benefit from answers to the simple(?) question:  Which would YOU choose, and why?  Like lots of people, I'd really like to increase my data transfer rate from the hard drive.  Right now I have a 15ms 210Mb IDE drive (Seagate 1239A), and what I would say is a standard (not special, no cache I believe) IDE controller card on my ISA 486-50.  I'm currently thinking about adding another HD, in the 300Mb to 500Mb range. And I'm thinking hard (you should hear those gears a-grinding in my head) about buying a SCSI drive (SCSI for the future benefit).  I believe I'm getting something like 890Kb/sec transfer right now (according to NU).  How would this number compare if I bought the state-of-the-art SCSI card for my ISA PC, and the state-of-the-art SCSI hard drive (the wailing-est system I could hope for)?  Obviously money factors into this choice as well as any other, but what would YOU want to use on your ISA system? And how much would it cost?  Along those lines, what kind of transfer rate could I see with my IDE HD's if I were to buy the top-of-the-line IDE caching controller for my 200Mb, 15ms HD? And how much would it cost?  I actually have a PAS-16, and could (what a waste I guess it would be...) hook up a SCSI HD through it's SCSI port which yields an optimum of 690Kb/sec. Actually, I have a borrowed 12ms Fujitsu HD hooked up through it now (and own the Trantor HD drivers for the PAS-16 SCSI port).  Is this SCSI port a SCSI-2 port?  How could I tell?  Is the Fujitsu 2623A a SCSI-2?  Are all SCSI HD's SCSI-2?  Thanks for any comments.
HELP!  I am trying to view .JPG files with my 386SX, 20MHz machine .  I have a STB-POWERGRAPH graphics card with 1024 X 768 by 256 colors, with 1Meg RAM on it.  I have tried CVIEW097 (with windows-- EXTREMELY SLOW), and DVPEG24. DVPEG24 doesn't work!  Even if I pick a lot of the "modes" that are supported by POWERGRAPH (so it says in the manual), it doesn't work when I try to view a picture... it only buzzes.  Anyone out there that can help me; give me suggestions?  I would really appreciate it!
A friend of mine needs spec for a used hard drive he just got: It is a Western Digital, IDE, 340 meg with 1010 cylinders and 12 heads.  We believe the model number is wd2340A, but we can't be sure.  It is a 12 ms, 3.5" model.  Any info would be appreciated, either from somone who knows, or maybe western digitals phone number
Hi,  I just got a problem, I have a cheapo 2400bps modem which I use to connect to my university, but I get too much garbage on the screen. I do know it's because the noise in the line (I can actually hear it).  So my question is will an error correction protocol help to eliminate this garbage?, my modem doesn't have any of these on hardware, can a software implemented protocol do the trick?  Thanks.

The difference is that the 16550 got bugs while the 16550A can be used whithout problems even in fast serial communications.

Dont rely on benchmarks. They often show incorrect due to different    TSR programs.  2. SCSI often needs a driver to get the speed from the card.  3. Make sure the card is operating in synchronus mode which is 2x faster.  4. You can disable disconnect and get some kB/s but just to loose the mouse    or other int`s when diskaccesing.  (I get 2.3MB/s with DX50 LB and SCSI LB and Maxtor LXT340SY - Coretest) (I get 1.3MB/s                                              - Sysinfo)
I have just installed a Diamond Stealth 24 ISA card in a '486DX2-66 system with 256K cache, and 16 megs of memory, that gets about a 126 SI 6.0 CPU Benchmark rating.  Using the 1024x768x16 color driver under Windows, I am getting a Winbench Winmarks rating of only about 9.5 Million.  Since I have heard that others get 15-to-16 million for this card, I assume that something is very wrong with my setup.  What are some possible causes of the card slowing down like this?  I ran the Qualitas ASQ diagnostic program on memory, and I noted the following memory timings on my machine:  ASQ v1.30 by Qualitas  SYSTEM ANALYSIS  Mon Apr 19, 1993  11:43:49AM    page: 1 --------------------------------------------------------------------------------  ACCESS TIMING       Hex     KB     KB   Access Speed Ratio (%)   Start  Start   Size  Time us 0   25   50  75  100      00000      0     32      396 ******************   00800     32     32      598 *****************   01000     64     32      157 ********************   01800     96     32      180 ********************   02000    128     64      157 ********************   03000    192     32      165 ********************   03800    224    128      156 ********************   05800    352     96      169 ********************   07000    448     32      153 ********************   07800    480     32      188 ********************   08000    512     96      158 ********************   09800    608     32      171 ********************   0A000    640     96     1221 **************   0B800    736     32     1581 ************   0C000    768     32      312 *******************   0C800    800     96      154 ********************   0E000    896     64     3957 *   0F000    960     64      312 *******************  Note two things on this chart:  1) The video memory appears to be many orders of magnitude slower than system memory.

Organization: Compact Solutions, Canberra ACT Australia  I have a floppy drive which has developed "General failure" errors. (It's a Teac 1.44Mb 3.5" drive).  I took it out of the machine and noticed it was very dusty. I used a high powered air can to blow all this dust out and it's quite clean now.  However, it didn't help the problem.  I've also identified that when the machine boots (and the drive seeks for a boot disk), the head movement during this process is now approximately half the length of the original time.  What I mean is the period when the drive light comes on and the heads move from their retracted position out to the track containing the boot sector.  Is there anything more I can do to try and save this drive? I'd prefer not to shell out $100 for a new one if I can help it.  Thanks!

System manufacturers had MAJOR problems solving the electromagnetic  interference problems with 486DX/50 systems.  Getting an FCC-B (home use)  certification required additional shielding in the system.  2.)  HEAT...a lot of people seem to be installing heat sinks and/or cooling  fans on their 486DX2/66 chips.  I would guess that the 486DX/50 ran  temperatures inside the case even hotter.  And heat is the enemy of system  reliability.  Ed

I attempted to low-level format a WD 43MB disk about a year ago.  When I understood my error, I contacted WD.

This way, if the relay breaks, my drives will still work.  It works fine, but you may still need to change the CMOS before the drive switch will work correctly for some programs.  rp93

I think they are trying to get it out by the end of this month, when it is released though it'll be in limited quantities, I think they have quite a back order right now (the 2 megs version will come out a bit later).

It can also do 640x480x16 mil. and 800x600x16 bit at 90Hz, too bad I don't have such a high bandwidth  monitor like yours ;) ;) (most of those modes need a 78khz monitor, otherwise you'll have to use a lower refresh rate)    If you want more info. about the coming Graphite VL, you should go to the IBM hardware section on Compuserve (IBMHW), in the video sig.  There're several Hercules reps there that are very helpful.
