I have an old sys m569 motherboard with “shared video memory “ I remember starting it with 4mb installed 2x2mb Simms and an AMD PR133 You could adjust the video buffer from 256k-4mb Windows 95 will run on 3.75mb I know for certain and 98 on 8mb I could not get 98 to start on less than 8mb, but I …

My only point is uncached clk2 sdram is indeed faster than uncached edo This means it has an advantage on motherboards unable to cache more than 64mb And I have used 70ns FP Simms on a fake pc100 SIS motherboard running at 90mhz FSB back on “the day” All that happened was terrible memory timings but …

Have you tried himemx instead, I know it sounds dumb but maybe that one would work around this issue automagically as you say

Many say EDO and SDRAM run about the same speed on s7 but in reality Speeds beyond 66mhz + SDRAM and more than 64mb make things run a little better than edo since you need to pipe straight off the uncashed ram

It may be possible to add VLB bus off the 486 cpu socket, the same way you can add a passive ISA backplane off the right cpu pins on an 8088. Trouble is you would need a cable like the 80pin ide cable that could work around all the noise issues and god knows the shape and ground plane issues that …

A VX supports 32 chip low density 64mb SDRAM It’s not a discovery and right in the spec, Sadly those are very rare so you almost always need to use a more common 256mb low density dimms at part capacity to make it work at partial density 64mb, it should be perfectly stable EDO dimms are just easier …

Does your motherboard have a bios option for a memory hole? On ISA systems I believe between 15-16mb area some devices grab a swatch of memory

After the 486 era was mostly over 1997+ I got a bunch of ISA micronics dx2-50mhz systems I didn’t have many oscillators but found the easily went to 66mhz, I also found I could speed up video a lot overclockong the ISA bus

.6 micro meter PODs had more cache and didn’t scale very well for some reason The second integer unit is also disabled They planned a dx4 pod overdrive as well but the things were expensive and sold poorly. From rumors the POD project took too long and was hard to optimize and like many intel …

A VX can support a full 64mb edo stick, you need to get a true low density double sided one though.

I already have a very old one that works even on an xt but found one in the box, still B&W but now Windows compatible. These are a little rarer due to their age just curious if they are of interest having. Thanks

I don't like the W10 UI, but then I also didn't (and still don't) like how Windows 7 merged the taskbar and the quicklaunch panel into a single interface. It really bugged me when I started using it, but I eventually got used to it. The same will probably happen with W10. I just hacked it to look …

Yep, but I thought we're discussing a machine with TGA only. The TL tech ref says that for a 768kb machine, the CGA memory window at B800 maps onto memory at that location. So maybe for CGA modes at least, Axxx is unused and has memory accessible from the CPU. 640 x 200 x 4 / 8 / 1024 = 64kb Never …
