Change partition type to 'c' (fat32+LBA); check that BIOS is set for
(AUTO or USER) and LBA.
Regarding the PIIX4, I reran basic throughput read tests on a more
recent UDMA5, 5400RPM Maxtor on the PIIX4 and HPT366 (Abit BP6 +
2.2.19p17 + ide.2.2.18.1221.patch) chipsets.
Since pin 30 is plugged on my ATA66 cable, I used an Asus P3B-F as a
ATA66+PIIX4 sanity check. Neither the Abit or Asus PIIX4 controller
would go higher than UDMA2. Although hdparm -i reported UDMA4, neither
the -tT or dd tests demonstrated faster results. The kernel logged
'ide0: Speed warnings UDMA 3/4/5 is not functional' when attempting a
setting higher than UDMA2 on the PIIX4.
Apparently IDE drive technology has improved over the last year,
however real world PIIX4 speeds are still in the 14-19MB/s range.
UDMA2/PIIX4 16-21MB/s
UDMA4/HPT366 19-28MB/s
