I believe those caps are for the ISA slots, which would explain why the rest of the board is still working. If I had to guess, the one that failed there is probably for one of the 12v rails, so any ISA cards that utilize that rail would of course not work. Does the motherboard have a manfacturer and …

A Linux distro with a lightweight GUI would probably work pretty well. Otherwise depending on how comfortable you are with Linux, you could even use buildroot to create your own optimized Linux installation by cutting out things you don't need and tailoring things to your specific hardware.

Missing board: PCChips M925ALU. The main difference with the other M925 models is it has the higher 533MHz FSB (P4M266/A northbridge -- the "A"), onboard 10/100 LAN (the "L"), and the onboard USB ports (the "U"). The manual for this model also mentions all of the other M925 models and their …

MS-DOS 7.1 (from Windows 98) was the first official MS-DOS version to support FAT32 (out of the box). As far as I know the only existing solution for FAT32 support on MS-DOS pre-7.1 is using DRFAT32, which is a part of DR-DOS. However from what I understand that implementation is buggy (although …

Don't the ESP-8266 based serial to wifi adapters do that already, convert the protocol onboard? I've not seen an ESP-8266 or ESP32-based serial to wifi adapter that provides PPP onboard. Probably due to resource limitations on such embedded devices. Using a Pi would be a lot easier and would much …

I believe at least one difference (not considering engineering samples) is the iDragon has a 2.0V core whereas the mP6 had 2.8V. It also seems the iDragon used a newer process (180nm) compared to the mP6 (250nm)? Since the iDragon tried to target the embedded/SoC market, both of these changes make …

Additionally the user guide mentions needing support for long file names to be able to load the fonts, so you may also need to make sure your DOS installation has support for it (either natively or via the "doslfn" program).
