As Joseph_Joestar said, tests from Phil's Dosbench should be started in plain DOS mode (not in Windows 9x DOS box). To get speed boost you should run FASTVID before. Although windows video drivers are doing same/similiar thing as FASTVID, Windows itself can cause slowdowns. Check if your VIA based …

You may try riser like this ...but probably not in the standard AT case. BTW. Onboard soundcard is not that bad (it is rebranded CMI8330).

Yes. I had this board in the past. Even Cyrix 5x86 CPUs are supported OOTB. Here you can find more information http://www.win3x.org/uh19/motherboard/show/1074

If there is no such option in BIOS, or you can't access BIOS setup easily, I would try CMOSer from here https://www.sac.sk/files.php?d=16&p=16

This machine probably has no high memory (above 640kB) at all. So himem.sys can only consume part of conventional one 😀

Oops... You are right. Pinout is totally different. Shame on me... They "may" work on your board with oposite adapter (to this Willem one). I don't know about bootblock keyboard shortcuts :( I only remember that for some older Toshiba laptops there was LPT/Parallel plug for invoking flashing from …

I'm afraid that choosing another similiar memory type may not work in this case :( You may try however to buy another similiar supported memory like AM29F002 or M29F002 or AT49F002 with "top" bootblock location and try to use it. What else comes to my mind. If bootsector isn't broken, you may …

If you add necroware's MCE adapter https://github.com/necroware/mce-adapter it should work quite well ! There is also very interesting attempt (using Rapberry Pi) here MDA/CGA/EGA/VGA to HDMI using Raspberry Pi Zero

This Intel flash is somewhat specific (12V programming voltage, bootblock position and size etc.). In this crossreference i.e. there is no direct replacements from SST. You mentioned that you have user manual for this board. Please check if you can use another flash instead. I remember that on …

Probaby you can use any generic 2MBit Flash (with 256k x 8bit organization). Programer of choice is ofcourse TL866 😀 Do you have another graphics card (ISA, PCI) and good known PSU to check before ? ISA/PCI POST card is also nice-to-have for diagnosing.

I would choose one with Intel BX chipset. You won't regret choosing it, unless you love to play with drivers, BIOS and chipset tunning :) They are just solid - rock stable and top performance. Build and work/play. Someone may say they're boring - not much to improve. For CPU - faster is better. P II …

ZIP memory chips should be 20 pin, that's for sure. Organization should be 256k x 4bit. Timing ? Chips onboard are 45ns. It is hard to find ZIP memory "that fast " Cirrus Logic mentions 70ns in specification (from here ) for 45MHz memory clock. I think we can asume 60ns for 50MHz MCLK (which is max …

Thanks for the links, I'll take a look. About the cache memory, the book says this: CACHE MEMORY 128 KB of second-level cache memory may be installed (except in the 486/25VL). All four chips must be installed. My model is 486/25VL, so it seems that the missing chips could be the ones needed for …

Now you have 512kB graphics memory: 4 chips in organization of 4 x 256bit v53c103 . I suppose you have to buy 4 ZIP chips of the same organization: ebay search You are right regarding cache sockets. For cache memory just buy 32kBx8 chips just like on the picture I linked before , but... I'm not sure …

According to your motherboard chipset datasheet VL82c480 your system is ISA only :( But CL-GD5428 is fast ISA graphics chipset and you can probably double its memory throughput supplying ZIP memory to empty sockets (between CPU and graphics chip). To even more boost system performance you can solder …

Check your BIOS chip (2MBit vs 4MBit). Maybe you can flash bigger BIOS on it ? If not, you can always buy chip with bigger capacity and try hotflash (with Uniflash - tried that many times with success).

If you only consider DOS and Windows 3.11 then Cirrus Logic you have is all you need. It is one of the faster and most compatible DOS graphics cards (it's better than ATI ones according to this table https://gona.mactar.hu/DOS_TESTS/ . Moreover, almost all DOS games uses GFX card as simple …
