Got another old PC, this time it's a Pentium 2. The PC seems fine, could run Win98, test, games.

But... I cannot flash the BIOS. AWDFLASH v8.99 says the part number is not right, UniFlash 1.40 says it cannot recognize the flash chip and the flashing menu items are grayed out (tho I can backup the BIOS into a file).

See the pictures.

I tried BIOSes from the Asus website (https://www.asus.com/supportonly/p2-99/helpdesk_bios/) and from The Retro Web.
