The manual says that U28 TAG must be removed in this configuration, try that. Or perhaps it is U27 (=error in the manual). Btw, you need to test the cache size in DOS as well, with cachechk or a similar utility. On a sidenote, the BIOS of certain motherboards with fake-cache always report the same …

No, I think you did not specify "DIP 28" in your ebay search. You need the sleek chips 😀 I.e. https://www.ebay.com/itm/2pcs-UM61256FK-15-UM … GQAAOSwwzhZU03T

If speed is not important, then you can skip on the TAG question as the current TAG configuration supports 256k cache, too. If you want faster cache, TAG swap is necessary. In this case, it is indeed a bit of a gamble because the motherboard MIGHT be picky about the TAG. When the cache is working OK …

You can easily investigate the type of chips with a little googling as the chips are clearly labelled, socketed and almost certainly, not fake :) You have a double-banked configuration of 8kb chips, 8 pieces = 64 kb. It is a very early 486 board, using dual TAG chips - but it is important that …

The EMU8000->MPU-401 redirection is very limited under DOS as AWEUTIL can only work with real-mode stuff, not with late DOS-era games where you would expect/need it the most. These later games use either the quasi-standard DOS4GW or their own proprietary extender (for example JEMM(?) in Strike …

This GD5429 is a great chip, plays very nice on CRT monitors. Most cards have nice vibrant colors and good centering. Has good compatibility with a wide range of DOS games and it is definitely on the speedy side - it is even tuneable/overclockable with mCLK and stuff. As I recall it has good VESA …

Hi and W.O.B.!

The original GF1 is the logical choice for a mid-range 486. Of course, it is not as capable as the AMD chip, yet most GUS-aware games and demos of the period support it "natively" (there is some mambo jumbo here and there, but at least you do not need to patch each and every old game - remember, the …

Thanks for your leniency, Plasma. Miraculously, I was not circulating the source code 😵 I will try to keep better records of acquisitions in the future. I hope you will stay on these forums in better spirits... also that I can save (some of my) face in spite of this fiasco.

What said above. The main culprit is the poor power supply on the AGP slot. Additionally. the more stress you put on the motherboard by adding RAM and using an older K6 III processor or overclocking it, the more frequent crashes you get. You still might have luck with a Geforce FX, like me. But not …

This dilemma is far more difficult than it initially seems to be. "vanilla" installations are pretty much vaporized after deploying one or two software suites or games which replace core system components with their own, many do this without dependecy walking and making backups of dll files and …
