SubjectRe: ide/disk perf?

I have it enabled, however I never used any HPT366 controller, so YMMV.
The BX chipset is what I tested the most.

Looks very similar to my own settings

CONFIG_IDE=y
CONFIG_BLK_DEV_IDE=y
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_IDEDISK_MULTI_MODE=y
CONFIG_BLK_DEV_IDECD=y
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_IDEPCI_SHARE_IRQ=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_IDEDMA_PCI_AUTO=y
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_BLK_DEV_PIIX=y
CONFIG_PIIX_TUNING=y
CONFIG_IDEDMA_AUTO=y
CONFIG_BLK_DEV_IDE_MODES=y


But I only do

hdparm -qu1c1k1 idedevice

at boot time. Also, I've found

append="ide0=autotune ide1=autotune"

in my lilo.conf, left from earlier testing session. Remarks in ide.c say it
only has influence on PIO modes, so unless the comment is obsolete I guess I
could as well remove that line.

Best regards,
Pierre.
