do you have opened the scope to physically check the motherboard capacitors ?? they could play some tricks, and they are not easy to change ...
ill check the 2 links you provided
Hum made by powerquest, and the second iso as one file mentioning tds5k in it
![Huh? ???](https://www.eevblog.com/forum/Smileys/default/huh.gif)
? not even sure it's the good images for your scope ?
I would redo a full os install say from an genuine w2k cd-rom, or the tds7k zip file link i've sent you, you have an os iso in it and the w2k sp4 in it, even the os serial is there ...
Burn an cd-rom at 4x ... low speed
For the serial you should have the sticker on the casing
Your posted cdrom listing / index / folders have the needed drivers you will be able to use
Normally you will need the vga drivers, the touch screen drivers, front panel drivers, lan, audio, ICH (intel chipset) ... and the one for the TVIA board something loll
the p25 bios can be upgraded from a windows os ... if i recall it can wait until you have a fully working os
Do you have a separated "normal" ATX computer board and a agp/pci slot separated interface board, or you have one edge of the mainboard who slot in a backplane board on the side
I'm sometimes confused between the A and B models, since you wrote an non B model loll
But OS side is the same
If the cd-rom is ok you should be able to boot from it ... win2k ones where bootable if i recall
If you finally manage to get a os boot
Xdev's tds7000 non B softwares and drivers ??
