You can add a XT-IDE Bios and boot from a HD or CF that you have prepared in another PC or Emulator. Xt-IDE does not care about the CMOS settings. No need to get the floppies running. Or you use another main BIOS, MRBIOS for 286 may be a good choice.

The POST-card also looks interesting, will dump the ROM later Good luck with that. As there is no sticker over the EPROM window, you'll be lucky if the data is complete, if it's not fully erased (depends how long it's been in the light with the window open to that light). Yes I noticed that. See …

No, this BIOS image is surprisingly still missing. I have hoarded over some time an extensive collection of MR BIOSes. I just purchased the board with AMI and looking forward to an upgrade, but since I paid a lot of money for it I am afraid to ruin it on the very next day. Is there anything in …
