Re: [gentoo-server] SATA again...

[lema]

I have several servers with a Intel 875PBZ motherboard, one SATA disk of
160GB, and a CD-ROM. In the bios there is a 'Drive Configuration'
section where you can choose your 'ATA/IDE Configuration' as 'Enhanced'
or 'Legacy'. The first one gives you the 2 PATA channels plus the 2 SATA
channel for a total of 6 devices (2 SATA and 4 PATA). Booting from
Gentoo-2004.0-universal CD with this configuration + RAID disabled, the
SATA disk is shown as /dev/hde (or /dev/hdf). If you want (for any
reason) to have your SATA disk as /dev/hda you should change to the
Legacy option selecting the configuration whith the 2 SATA channels +
the secondary PATA (where you put your CD). Booting in this
configuration (RAID disabled) shows the SATA disk as /dev/hda and the CD
Rom as /dev/hdc.
This is a copy&paste of the section in dmesg where the IDE drives are
detected whith a 2.4.24 kernel:

        Uniform Multi-Platform E-IDE driver Revision: 7.00beta4-2.4
        ide: Assuming 33MHz system bus speed for PIO modes; override
        with idebus=xx

        hdc: attached ide-cdrom driver.
        hdc: ATAPI 52X CD-ROM drive, 128kB Cache
        Uniform CD-ROM driver Revision: 3.12
        Partition check:
         /dev/ide/host0/bus0/target0/lun0: p1 p2 p3
        ide: late registration of driver.

When I tried to boot from a 2.6 kernel, the SATA disk is not detected at
all in any BIOS configuration.

Hope this can help and not confuse...
