Hi
I just applied this patch against ac7 (hand apply of the first
chunk, but easy to solve).
I have found that my system boots with this patch, but It only gets
ATA33 mode (amd7409 chip) with my disk (Seagate Barracuda
hda: ST310220A, ATA DISK drive). Without the patch, if I use the overaid option
(ide0=ata66) I get ~26MB/s (hdparm -t test). Without overide I get
around 16MB/s. With this patch I get 16MB/s, it doesn't matter if I
use ide0=ata66 or not.
Later, Juan.
PD. I don't know *where* the patch got mangled, but for me it appears
1 in several places
+byte 1word_dma_ok = 0;

the changes was consistent in all the patch, then easy to fix.
