..... It's not a RAM issue, I have 512 MB on it. 512MB RAM is very little for Windows 7. So I would not try below 1GB, so the socket 7 platform is out. But I understand you are just checking if it is possible. Like Windows XP on a 486-Pentium Overdrive. That "runs", too. There are socket 7 …

One of my old super 7 boards had 768mb Unofficially I think it would go full 1.5gb as it did support 512mb dimms although at the time I only had one. If I had to guess 7 would run better with more ram

Yeah I just bought a Compaq 1mb board. Not ideal size but the price was right (less than shipping). It'll get me by for now. But man, when did shipping get so expensive! Ah well, first world problems... How much ram did the 286 have? A Compaq doesn’t just use more ram if you install it. For …

Although I am no help it would be interesting to compare the last Rev 286 to the very first rev a’s that supposedly ran XMS faster.

Thanks for the replies. So it is a Deskpro 386s, which is the older-style 386 with no slots on the board for SIMMS. Looks like I would need to find a Kingston KTM-16AT or an unobtanium Compaq board that was made for this model. But that being said with 1mb on the board and me only wanting to run …

Wow guys! Too bad AMD didn't keep the "486...something" name on the chips. For a 486 purist like me, the latest and fastest 486 remains the AMD 486 DX4-120. On the faster ones, it says 5x86, therefore, it doesn't feel like a 486. If you want to be pedantic a chip that actually said 486 and 133mhz …

You don't want ISA memory expansion boards in a 386 except as a last resort for performance reasons Compaq 386 doesn’t allow normal memory expansion options (no simms, no dipps) Either a proprietary unobtainium memory card or isa . The question is if you already have4mb/5mb on the planar is it …

VLB doesn't require BIOS changes more than any other chipset tweaking options but PCI requires a ton. Perhaps that is also why VLB lingered for a while. Circa 1993 PCI was extraordinarily expensive to include from a boardmakers standpoint. (It was only trying to be cheaper than mca) There was …

Having shopped for 486 systems including name brands 1994-1995 I would say pretty much every name brand plastered VESA LOCAL BUS GRAPHICS all over the sales card in front of the machine at the store. So Many name brand 486 systems had VESA local bus. I would agree Most didn’t have a slot. That said …

VLB was a cludge during a specific timeframe when faster bus options were too expensive and ISA was too slow. A 64 bit 66mhz VLB 2 was developed but nobody adopted it. Even though it was present on boards 1992-1996 it had very little attention after 1993 which really stumped owners of systems with …

8kb AMD DX4 - 100mhz chips exist. And of course 5x86 chips and Intel dx4 overdrives Ran under clocked these chips will sometimes last years at 5 volts (sometimes not). There are overdrive units that fix the voltage problem Either should be compatible and won’t require overclocking

Something doesn’t like being overclocked. Very strange for 1991, not even able to click 33mhz When you move back to 50mhz everything is fine? There used to be strange oscillator speeds 55mhz 60mhz etc, you could try to see if the board will overclock at all. There are also 75mhz and 100mhz …

Voodoo 3 are cheaper and if you have an oddity you can overclock the pci bus to 60mhz with one. If your not into hardcore 5x86 any period correct PCI is fine, I preferred ones that supported Tsing video and mpeg codecs.
