This driver supports PIO28 only.

Tested and approved!
According to the datasheet of the drive (IBM-DTCA-24090) it is indeed LBA28.

Do you need any more information?

What are you mean "approved"? How about hangs?

No more hangs. FAT32 access works fine.

Since there is not much difference, I think the problem was in 400 ns delay of status port.

So, you want me to add LBA28 support to the trunk driver, or that's enough?

The main difference is that DMA is disabled in this driver, or am I missing something?
