Monstertruck Madness 2 comes to my mind. ... I haven't tried, if it works on XP+, but it's definitely Win95 era game, that had software mode and accelerated modes. (If i still remember correctly 😀 )

SD->IDE adapters do exist. They cost a bit more, because it must be intelligent enough to actually convert the SD card's protocol to IDE protocol. Random quick searches, definitely not the cheapest offers: https://www.ebay.com/itm/44-Pin-Male-IDE-To-SD-Card-Adapter-BN-U0/282271953975?epid=1469258947 …

CF/SD -> IDE are good. CF is direct connection, SD need some intelligence, because it doesn't share the IDE protocol. Some motherboards will not see harddrives larger than ~500MB. Solution on Hard Drive overlay like OnTrack or EzDrive. (At boot time, modifies bios, then exits, therefore no ram usage …

Cyberdyne, you mean that backup ups kicks in only when input fails? Line interactive one is turned on all the time, correcting the voltage. (Though, its not creating the whole output power from scratch) https://www.youtube.com/watch?v=Fj7e3WGUKO8

quicknick, Thank you for the upload! As i haven't still be able to source the bios by model name (only this 25R version, not 25N), you might have just saved that motherboard of mine.

arteq, I've found that first link. Thanks for the second one. It somewhat confuses me, is the 25R bios meant for my 25N as well? I have downloaded it and waiting for chips to arrive so i can burn it on, but i'm not really sure it's the right bios image...

quicknick, Mine has also a sticker labeled "025N2" so i think it's a match! When i get home, i'll make a picture of it. But most notably, it's the SY-25 motherboard WITHOUT the 3.xx V power regulator in place. (So non-"P" version, i think) Any chances for you to get the bios image off from your …
