Few thoughts came up. Will a regular hard disk/CF card be detected as secondary master? What if you set the CDROM as secondary slave? Will it be recognised then? Perhaps with a hard disk as primary if your bios does not accept a slave drive without master. What if you set an extra delay for …

Is the cpu Coppermine or tualatin? Anyways, I think the gf4 ti 4600 or 4800 will be a great choice. Fast, Windows drivers can still be pretty low version ( =lower CPU impact) and support is great. Also vesa is supported very well, although not as good as the slower TNT(2) and gf2. If you go voodoo, …

What controller cards so you have in your system? Can you remove any non vital ones? It may be CPU related. Could you reseat the CPU for 30 more times? Any dust or rust should be gone then, to make sure your contacts are ok. Also try to reseat cache (if possible on your board) and reseat your …

This may cause the delay... The motherboard may be re-checking over and over which CPU is used, but fail to identify it. Mentioning 100MHz down not mean the CPU is running at this speed. The bios simply may not be programmed to correctly report the speed. No Intel dx4 was intended to run at more …

(...) But a card like a Matrox Millennium PCI with WRAM on a late 486 would be something I hope to see build sometime to see how well that card should help the cpu working in a "heavy" o.s. like Win95. My PCI 486 has one. It is working like a champion in dos and Windows 3.11 now. The Intel Ninja …

In my opinion, the words "GUI" and "ISA" can only exist in a sentence when choosing between them. For usability I'd go for at least VLB or PCI (or something EISA? Opti bus? Never used them). On the other hand, the best ISA cards with GUI support I used are the S3 928 and cirrus 542x. So about the …

Large hard drives and DOS: DOS 7.x is the way to go. I believe PC DOS 7 and up do support fat32 as well, and are dedicated DOS, not linked to win 9x. Not tested myself but these should be able to install windows 3.1x without hassle. To get a good DOS 7.x install I did this: - boot any pc of VM with …

The Athlon will certainly be overpowered for win 98 gaming. That's a good thing, as it will run everything you'll throw at it. At least if you can find the needed drivers for the chipset. Pair that with a high end AGP card like the ATI 9800 (or 9600/9700) and you'll be ok. Otherwise I'd stick with …

I could look if there are some pods present if the voltages will drop to much with more load.

Also I don't have the …

Voltage on my multimeter varied between 11.69 and 11.73 volts. The lower voltage was when something happened, ie when system post was going on, when switching from 2D to 3D with 3Dmark. But recovered soon. I'll test again some time and attach some extra drivers to see what happens.

To stay period correct these mods seem legit more or less. CGA was the original upgrade from MDA, so possible indeed. For correctness a Hercules card would be more logical as these became available not long after the pc XT (still period correct on a 5150 if you kept it for years). The VGA Wonder 16 …

Could you try to remove all non vital components like the network adapter and see if that helps? I guess it can be an IRQ conflict between the network adapter and the ps/2. Does a serial mouse work? That could be a second option... But no fancy light down under then...
