I have a 486 DX 33 motherboard in my pc that i'd like to speed up.  I'd rather not replace the whole motherboard, instead i'd like to know if i can use a DX/2 66Mhz cpu. The BIOS is late model AMI, circa 1991, and the system crystal is approx 66.3Mhz.   My question is, can i just replace the original 33MHz cpu with the new DX/2 cpu? If its possible, will there be a need for extra cooling devices such as heatsinks and / or muffin fans??

I saw in this months PC or PC World an ad for computers using IBM's 486SLC. So I don't think IBM is restricted in selling their chips, at least not anymore. A clock-tripled 486, even without coprocessor would be great, especially with 16k on-board cache. Make it 386 pin-compatible, and you have the chip upgrade that dreams are made of :-)

Hi,  I would like to hear the net.wisdom and net.opinions on IDE Controllers. I would liek to get a IDE controller card for my VLB DX2 66 Motherboard. What are good options for this (preferably under $200). It MUST also work under OS/2 and be compatible with Stacker (and other Disk Compression S/W).  Please advise .....  Divya --  Divya
Hello all,  You, the Net, are my last resort, or I'll just change my job :-) This might be a FAQ (e.g. mixing controllers) but haven't seen any.  Sys: 486/33, AMI BIOS, and your run-of-the mill multi-I/O card with serials/paral/floppies and  	- IDE controller "clone" Gw2760-EX 		there are no jumpers affecting the HD or ctrller :-(  	- Quantum ProDrive LPS (3" 105M type 47: 755cyl, 16hds, 17spt).  Pb: I want to bring in this (2nd hand, neat price): 	- Maxtor XT-B380E (~330M, <15ms, BIOS type 1, ctrller manages 		the real geom: 1630cyl, 8hds, 52spt) 	- Western Digital WD1007V-SE1 ESDI ctrller: no floppies. 		(jumpers set IRQ 14/15, hw port addr 1F0/170, 		and BIOS addr CC00/C800, and other floppy/format stuff)  Goal: have the WD ESDI as a secondary/controller and have both disks  simultaneously working. Being able to boot from the ESDI too would be  a nice bonus but is not expected.  Ultimate goal: have room for Linux et al. Ex of scheme I have in mind: boot from IDE (HD or floppy) and mount the ESDI as root. Not booting from ESDI, or even from HD, is acceptable.  I have tried numerous (all!!) combinations to no avail. They work alone, or can coexist witout hang-ups but can't access the ESDI or the IDE,  depending on setup/jumpers.  Useful suggestions might be: - How do I tell the BIOS setup about two ctrllers (I guess the 2nd HD is expected to hang off the same ctrller as the 1st). - Do I need some driver to make it work? - --- " --- some new BIOS/chip for any of these cards? - do I have to buy another controller to make them HDs happy? IDE is cheaper; ESDI is hard to find and rather costly. I'm not  rich or I wouldnt' try to scavenge around, so soft slns are preferred. - adapters of some sort; I can hold a soldering iron, and can change a chip or put a jumper!  Also useful: - BBS or Hot-line of Western Digital. - ftp archives with relevant info. - expert stores in Toronto, Ontario area (that would be a miracle! haven't seen any really knowledgeable ppl in a while) - any hints into inner workings of the system ...  - anything else that helped you in similar situations (prayers :-) )  Direct or posted replies are ok. 	Many thanks, 			Cat.

This is normal behavior for these drives (and many other models). The drive is doing a recalibration -- adjusting for temperature changes. If you leave the machine on the frequency of the recalibrations goes way down.

Think!  It's the SCSI card doing the DMA transfers NOT the disks...  The SCSI card can do DMA transfers containing data from any of the SCSI devices it is attached when it wants to.  An important feature of SCSI is the ability to detach a device. This frees the SCSI bus for other devices. This is typically used in a multi-tasking OS to start transfers on several devices. While each device is seeking the data the bus is free for other commands and data transfers. When the devices are ready to transfer the data they can aquire the bus and send the data.  On an IDE bus when you start a transfer the bus is busy until the disk has seeked the data and transfered it. This is typically a 10-20ms second lock out for other processes wanting the bus irrespective of transfer time.  >  > Also, I'm still trying to track down a copy of IBM's AT reference book, > but from their PC technical manual (page 2-93): >  > "The (FDD) adapter is buffered on the I.O bus and uses the System Board > direct memory access (DMA) for record data transfers." > I expect to see something similar for the PC-AT HDD adapter.   > So the lowly low-density original PC FDD card used DMA and the PC-AT > HDD controller doesn't!?!?  That makes real sense.

Hi. I recently switched my old Amiga 500 with a 486DX-50. My computer configuration is :  486DX-50 Mhz. 8/256 kB EISA (Micronics Motherboard ASIC EISA 50Mhz) 16MB Ram ST3283N 248 MB Harddisk, SCSI UltraStor24F EISA Cache Controller  When I use Norton6.0 Harddisk benchmark, I get a Harddisk data transfer about 980 kb/sec. and sometimes 1MB/sec. Is that good ? I thought that with EISA I could get about 2MB/sec.  Somewhere in the manual for my harddisk I have read, that some host  adapters need to perform a low-level format to optimize the harddisk  performance in that system, do I need that ? A guy I know, gets a HD transfer about 1.2MB/sec, and he has an ST3283A and a ISA 486DX-50, how can a ISA with the same system be faster ?  Is there anything that I can do to get a speedier harddisk ?                                           Thanks.  phantom@diku.dk   (e-mail is preffered)
All,  During my attempts to find out how the AT harddisk controller works I stumbled across I/O port 376h. The "normal" controller ports are in the 1F0h-1F7h range, so what does this port do???  The only information I have upto now about this port is that it is a write only port and the information you have to write in it is related to the number of heads on the disks.  Could somebody shed some light on this and give me the missing info.  Thanks,
I need to find how to program the WD7000 FAAST SCSI controller (A 16 bit DMA SCSI controller for the PC (ISA bus)). Can somebody point me in the direction of some low level docs on the net? Or will I have to get hold of the manufacturers? Who did actually make this anyway? Who will have the docs?  TIA.

Hello World. In posts I've heard about all of the bugs in the DSS24X and the drivers. Now I hear that Diamond ships BIOS replacements to some people, that fixes a lot of problems as well as new drivers. Can anyone tell me how to get mine?
Hi   I have heard about a linear mode for the ET4000, in which the 1Mb video  memory in linearly accesibly instead of the usual 64k pages. Does anyone know more about this ? How can I enable it and to what address is the video memory mapped to ?
Hi!     I'm busy resurrecting some old machines (hey, they're cheap and they work :)) and would be grateful for any help with the following card -  Magitronic - full length 8 bit memory only card. Has room for 8 rows of 256K dips for a total of 2MB RAM. Has an 8 position dip switch on it, presumably for addressing.  Does any kind soul out there have any docs or drivers for this beast? I'd be disgustingly grateful.                              Thanks,                                     Lee.

I have waded through the mass of SCSI-IDE posting, but I missed any answers to a question posted early on --  Has anyone (successfully) put both SCSI and IDE hard drives on the same system?  I am particularly interested in having the SCSI as the _boot_ drive.  For those who have managed this feat, I would appreciate a bit more information, such as what drives, which SCSI controller, and (if possible) what motherboard & BIOS (plus any other relevant info.).

Just my 0.02cents thought.... |>    Your machine will run at whatever the bus is jumpered to/CMOS is set to (usually wait states) regardless of what speed RAM is installed.  No motherboard can sense the speed of the RAM installed, unless you call failing as a sort of auto-sense.  This is how you can sometimes use "slower" RAM in a machine.  You either set the number of wait states to accomodate the slow RAM (in which case, all memory will run at that slower rate) or you reduce the wait states and take the chance that the slower RAM will act like faster RAM and you won't crash.  Putting faster RAM in won't speed things up unless you tell the machine it has faster RAM.    Mixing fast and slow RAM will not help you if you have to keep the bus  slowed down to accomodate slow RAM.

I'm afriad that's not true.  The monitor problem seems to occur whenever the 15" Mag monitor is put into 1024x768 mode.  I'm running OS/2 at 1024 and the same symptoms appear.  It does not seem like a video card problem as the Cirrus Logic 5426 chip and the ATI GUP seem to cause these problems... two VERY  different cards.

------------------------------------------------------------------------- Anonymous,  I saw a posting about the choice between 80486DX-50 and a 80486DX2-50. I was wondering: although a DX-50 is faster because of the path to it's external cache, shouldn't the choice be the DX2-50 as that one can be made to work properly with a local-bus? I mean, cache speed is one thing, but all your speed will be blocked during video I/O, so just get that faster...  I'm willing to speculate that the DX2-50 with local-bus will be 2-4 times  as fast as the DX-50 and probably as expensive (or cheap ;-)!

There are two 'problems': (1) the BIOS TOD routine which updates the BIOS clock uses only 1 bit     for day increment, so a second wrapping of the clock past midnight     will get lost if no one calls the BIOS to read the clock in the     meantime, and (2) the BIOS resets the day wrap indicator on the first 'get date'     call from ANYBODY (after the wrap indicator has been set). So     unless the first BIOS 'get date' call after midnight is done by     the DOS 'kernel' (which is the only part of DOS which knows how to     increment the date, the day wrap indication is normally lost. My guess is that Kevin's 'menu' system uses BIOS calls to read the clock (in order to display the time), and is hence the entity which causes the day wrap indication to get lost. Even if the 'menu' system 'notices' the day 'wrap' (which I think is indicated by a non-zero value in AL), there really isn't any particularly good way to tell DOS about it, so that DOS can update the day. The menu system 'should' use DOS calls to get the time, which would cause the DOS 'kernel' to do the BIOS call, and the wrap indicator would hence be processed properly.  Possibly, though, the 'menu' system can't easily use DOS calls for time, because DOS is not reentrant, and perhaps time incrementing ofters occur while the 'menu' system is 'inside' some other DOS call.
