H A Data-dma.cdiff 47272 Mon May 17 15:58:47 MDT 1999 sos Seventh update to the new ATA/ATAPI driver:

Fixed problems:

LS120 drives currupted data.
The workaround for drives not supporting upto 64K transfers
has been reworked. It works now both on LS120 & ZIP drives.

ISA only configs wont compile.
Fixed.

The ATA driver wont share interrupts.
Fixed.

The "unwanted interrupt" warning gave wrong controller.
Another lun<>unit messup from the newbus integration.

Some minor cleanups and rearrangements as well.

As usual USE AT YOUR OWN RISK!!, this is still pre alpha level code.
Especially the DMA support can hose your disk real bad if anything
goes wrong, again you have been warned :)
Notebook owners should be carefull that their machines dont suspend
as this might cause trouble...

But please tell me how it works for you!

Enjoy!
