I just booted 2.6.21.1 (the latest AFAIK) from my /dev/sda, which is a SATA |
| 11 |
drive. If it is sda*, it is the SCSI subsystem, otherwise it would be hda*. |
| 12 |
|
| 13 |
% dmesg|grep sda |
| 14 |
SCSI device sda: 156250000 512-byte hdwr sectors (80000 MB) |
| 15 |
sda: Write Protect is off |
| 16 |
sda: Mode Sense: 00 3a 00 00 |
| 17 |
SCSI device sda: write cache: enabled, read cache: enabled, doesn't support |
| 18 |
DPO or FUA |

So once again: if it is SATA, you need (in addition to the driver for your |
| 28 |
SATA chip): |
| 29 |
|
| 30 |
CONFIG_SCSI=y |
| 31 |
CONFIG_BLK_DEV_SD=y |
| 32 |
|
| 33 |
and, eventually |
| 34 |
|
| 35 |
CONFIG_BLK_DEV_SR=m |
| 36 |
|
| 37 |
And btw, even PATA is in the SCSI subsystem nowadays (my system has SATA hd, |
| 38 |
but PATA cdrom, attached to an Intel ICH6 chipset): |
| 39 |
|
| 40 |
% dmesg|grep -i scsi |
| 41 |
SCSI subsystem initialized |
| 42 |
scsi0 : ata_piix |
