I've been using this board for chips in testing coreboot on a asus p2-99.
Chips are correctly identified when hot swapped and do not get corrupted on power down.
Flashrom does _not_ work on the asus p2-99. It fails to find the flash chip. The p2-99 seems to be very similiar to the asus p2b, just with 440ZX instead of a 440BX northbridge and one less ram slot.
