I have tried with the new ROMs, as advised. The card is detected in the boot menu expansion board diagnostic. I have an ATA 250Gb IDE connected, no boot. The drive does work although no partition.
I have an Amiga 2000 arrive today that has a Buddha card in, I will try it out on that over the weekend.
just for clarity, would the Dom still boot if no hard drive was attached?
I have defo not plugged the card in “upside down”. Started my first job at 18 hack sawing XT cases to fit 386 25SX boards in and adding sound blaster cards to ISA while still setting IRQ & DMA channels by jumper before the days of plug n play.
will let you know the outcome.
thanks for your persistence!
