ASUS CUSL2 with Intel 815E (Solana), Maxtor 51536U3
>Description:
It appears that the IDE hardware of the Intel 815E, the ICH2, will
work with the same code presently in place for the Intel ICH (as far
as UDMA66, at least; obviously additional code will be required for
the UDMA100 which the chipset is capable of. I ascertained this
amazing fact by replacing all instances of the ID for the ICH
(0x24118086) with the IDE for the ICH2 (0x244b8086) with these results:
ata0-master: success setting up UDMA4 mode on ICH chip
ad0: <Maxtor 51536U3/DA6207V0> ATA-5 disk at ata0 as master
ad0: 14655MB (30015216 sectors), 29777 cyls, 16 heads, 63 S/T, 512 B/S
ad0: 16 secs/int, 1 depth queue, UDMA66
ad0: piomode=4 dmamode=2 udmamode=4 cblid=1
Creating DISK ad0
ata1-master: success setting up UDMA2 mode on ICH chip
ad2: <QUANTUM BIGFOOT TS12.7A/A21.0G00> ATA-4 disk at ata1 as master
ad2: 12243MB (25075008 sectors), 24876 cyls, 16 heads, 63 S/T, 512 B/S
ad2: 16 secs/int, 1 depth queue, UDMA33
ad2: piomode=4 dmamode=2 udmamode=2 cblid=0

ata1-slave: piomode=4 dmamode=2 udmamode=-1 dmaflag=1
ata1-slave: success setting up WDMA2 mode on ICH chip
