some had success by creating a bios error with killcmos loaded at boot, and some system would give you some basic bios access
or removing the coin battery for a day, or shorting the battery lead on the board once the cell is removed for a few seconds
on a other intel platform similar (if you can find one) you could create a bootable drive with the windows setup media, format the drive, and let it install all the way up to the 1st reboot
disconnect everything and continue on the other pc, but if the bios is very crippled, you may not be able to boot ..
was it booting on a flash card ?
i can not find specs for your system, do you have more details, pictures .... some logo while starting it, bios model / brand like award / phoenix etc ...
maybe you could or can find a very similar board, non crippled copy / dump the bios and flash a new bios in your crippled system
i did it for embedded systems, i only lost the parallel port on one occasion loll
