And I agree ;-)

it worked on Kontron 986LCD, but I don't have time to play with it (and I upgraded to a ryzen board). But actually I'm planing to use all semi-standard CMOS addresses for legacy/retro boards.

BTW does a boot from SATA CD/DVD works for you with seabios? (native IDE CD/DVD on PATA is in question too)
