I know this is going to sound stupid but which one is the cmos battery? I never seen a cmos battery that isn't just cr2032. I already replaced the real time clock chip but that did nothing. The battery is inside the Dallas chip. The replacement chip might not be compatible and/or its internal …

It's interesting. Some clicks take minutes, but for the most part it's surprisingly fast. And this is with only 5MB RAM. I guess having an accelerated graphics card helps a lot

Are you sure that the HDD is the original one? If it came from another machine with a different controller card, it often has to be low level formatted to be usable.

Another update: weedeewee was right, the 8 empty sockets were for an alternative memory population. After removing all the 256K and 64K DIPPs the board started to recognize the 256Kx4 chips I put there properly as 1MB, and together with the SIMMs the board now reports 5MB total (of which 640KB + …

Use rufus to create the bootable usb drive, make sure to safely eject it before unplugging Boot from your USB drive to DOS only, use fdisk to create a partition and format the internal HDD, run "sys c:" to install a minimal DOS to the HDD, use xcopy to copy the windows setup disc to the HDD, boot …

You could probably dump the BIOS using DEBUG or Navrátil Software System Information

Which mainboard and Geforce card are you using? Did you update to the newest BIOS and drivers? That definitely does not sound normal. You would get better performance with Win98Se or WinME. WinXP has a lot of overhead on Pentium 3 and older

Small update: the jumper next to the front panel headers is not for turbo on or off like I assumed, it's for disabling the on board DIPP RAM. With it unplugged the 2 SIMMs are recognized as 640KB+1024KB. @majestyk: Very nice restoration work. How long do those supercaps hold their charge?

All of them are pretty good. I'd keep the Realtek one as well since it has broader driver support than the 3com cards.

Seems like it really is needed for parity. I've now put some RAM (type MB81C4256A-70p) from a 286 board in the empty sockets, and it boots and recognizes the two 1MB SIMMs, the onboard 640K plus an additional 256K.

There is only one jumper on my board, the rest are labeled as jacks. The JP1 seems to be for clearing the CMOS and maybe activating an external battery. All the memory settings have to be configured inside the extended CMOS. But when I enable the banks 2+3 there the board stops POSTing properly. I …

Yep, I already got some SIMM sockets and 1M SIMMS with 9 chips to use with the board. The SIMM holder does not fit sadly so I had to remove the end of one of them. But either these modules are not compatible with the board or there is no good connection, because when I insert them the POST code gets …

That´s where you must know what you´re doing. Fortunately there are some 286 mainboard manuals with this chipset still available online. Did you find a manual for the memory settings in the BIOS? I have a very similar board also with no jumpers: _MG_1000_01.jpg The BIOS looks the same as yours, …

Looks like this system is stepping C2, so the smaller core. Is there a way to distinguish between a 120MHz C2 core that has been overclocked to 133MHz and a real 133MHz part?
