А нельзя ли поподробнее? А то я вот тут нашел всякие страшилки:
http://www.linuxmafia.com/faq/Hardware/sata.html:
Intel ICH5 / ICH5R family — supported in 2.4.22 and later kernels using the
stock kernel ATA piix driver (but that driver locks up in many cases), and
also (much more reliably) in the ata_piix driver in Jeff Garzik's libata
driver set, which is now (2004-02-25) of production quality. Alleged RAID is
proprietary software RAID
То есть использовать piix не рекомендуют из-за нестабильной работы, в другом
месте того же документа еще сказано что он на 10% медленнее ata_piix, который
в альтовых ядрах 2.4 есть (патч libata), но...
Among other things, you'll need to disable all kernel ATA support, since
libata uses the kernel's SCSI layers: http://gkernel.bkbits.net/ or
(somewhat easier to deal with) Garzik's periodic patchkits at
ftp://ftp.kernel.org/pub/linux/kernel/people/jgarzik/patchkits/.
I gather that libata is the only way to support SATA drives larger than 133GB.
(libata supports the necessary "lba48" ATA addressing extension starting with
kernel revision 2.6.5-rc2.) Also, Garzik has hotplug, random taskfile
submission (SMART support), and ATAPI under development for libata as of
2004-04-24. Last, Garzik has drivers for SATA-2 controllers under development
as of 2004-03-30.
То есть без libata диски >133GB все равно работать не будут, но с libata не
будет работать обычный ATA. А как же обычные PATA диски? А CD-ROM?
Кошмар какой-то. Вроде технологии уже второй год пошел, а нормальной поддержки
под линуксом нету? Куда же пошли миллиарды от IBM? Счетной палаты на них
нет...
