I obviously missed the start of this thread, but I use a 686b south bridge
and have no problems. You need to make sure you buy a quality hard drive, and
have a quality 40 pin/80 conductor cable (less than 18 inches long). I am
running my hard drive at ATA/100 speeds by forcing ata66/100 with:
/etc/lilo.conf
--------------
image=/boot/vmlinuz-2.4.3-12
label=linux
read-only
root=/dev/hda6
append="vga=791 ide0=ata66 hdd=ide-scsi"
/etc/sysconfig/harddiskhda
--------------------------
USE_DMA=1
MULTIPLE_IO=16
EIDE_32BIT=3
LOOKAHEAD=1
EXTRA_PARAMS=X69
And here are the results...
[root@beta root]# hdparm -ivtT /dev/hda
