Hallo !

Wo wir schonmal bei dem Thema sind. Ich meine, dass meine Platte an 
/dev/hda eine UltraDMA/66-Platte ist, irgendwie kann ich sie aber 
scheinbar nicht in den Modus bekommen. Hier dann mal ein paar Ausgaben 
von hdparm:

Ich hab in /etc/lilo.conf
append="idebus=66 ide0=ata66"
reingeschrieben, das scheints aber nicht zu bringen.

Laut Handbuch meines Boards kann der VIA vt86c686a aber UltraDMA/66.

Dann noch hier das, was in meiner Kernel-Config drin steht:

#
# ATA/IDE/MFM/RLL support
#
CONFIG_IDE=y

#
# IDE, ATA and ATAPI Block devices
#
CONFIG_BLK_DEV_IDE=y
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_IDEDISK_MULTI_MODE=y
CONFIG_BLK_DEV_IDECD=y
CONFIG_BLK_DEV_IDESCSI=y

#
# IDE chipset support/bugfixes
#
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_ADMA=y
CONFIG_BLK_DEV_VIA82CXXX=y
CONFIG_IDEDMA_AUTO=y
CONFIG_BLK_DEV_IDE_MODES=y

----------------------------

So, das ist alles, was mir an Info dazu einfällt. Bin über jeden Tip 
dankbar, mit dem ich meine IBM-Platte doch noch mit UDMA/66 zum Laufen 
kriege.

Gruss
