Hi, Thank you. It seems libata is compiled as a module in Kenshi Muto's custom installer (he is using a stock debian kernel from unstable). I confirm this by "find /lib/modules/2.6.15-1-686-smp/ -name *ata* -print" which shows :
/lib/modules/2.6.15-1-686-smp/kernel/drivers/scsi/libata.ko /lib/modules/2.6.15-1-686-smp/kernel/drivers/scsi/ata_piix.ko among others. Also the kernel config file in /boot shows CONFIG_SCSI_SATA=m CONFIG_SCSI_ATA_PIIX=m So I did create a file /etc/modutils/libata with content : add options libata atapi_enabled=1 and ran update-modules.modutils which did add the required line : add options libata atapi_enabled=1 to /etc/modules.conf However on rebooting the problem persists. Your identification of the problem seems to be right on target (thank you) as dmesg shows me : ide0: I/O resource 0x1F0-0x1F7 not free. ide0: ports already in use, skipping probe ide1: I/O resource 0x170-0x177 not free. ide1: ports already in use, skipping probe Does this mean I have to prevent ide-core, ide-disk, ide-cd modules form loading. Can I use modutils for this ? Could you kindly point me to any docs on how it is done ? (I can recompile my kernel only after I have a reasonable debian install with kpkg). In general what must one read to understand all the details about modules, initrd images etc ? I did try looking in the bios if there was any option to turn of ide compatibility mode for the cd/dvd. I could find none. The bios seems to be very minimalistic compared to those I was familiar with from a few years ago. There are very few things that can be changed. regards b thomas On Wed, May 03, 2006 at 03:48:09PM -0600, Stefan Srdic wrote: > Cool, yesterday there was a user who basically had the same problem that > you now face.
