	I really don't know but I just got it working with another flash card
(Note that the previous card was a Kingston 64/CF (slow one)):

Something which is very interesting is that on the 'slow card' the ata
driver is setting the transfer mode to PIO2 while setting PIO0 on the 'fast
card'. I find this behavior to be rather erratic. It is unfortunate that
using 'hw.ata.ata_dma' and the like we can't force PIO0 on the driver at
boot. It would be interesting to see ... Although someone could hardcode it
in the kernel (I may try it later)...

It seems to me that the slow cards are very disatvantaged in FreeBSD on the
Net4x line. First I had this 1-sector boot problem and then this READ
timeout issue. The first problem could be resolved by patching the boot1,
boot2 and loader but the READ timeout problem ... Well is unsolved right
now. Although it is worth saying that both problems can be solved by using
'fast' cards.

So, while I cannot say that the BIOS is not part of the problem, I have
serious doubt about the ata driver.
