 |
|
I have a 32-bit x86 laptop with separate IDE and SATA interfaces, see relevant "lspci -k" out below. As you can see the IDE interface is not being detected and no kernel driver is listed. The only thing on the IDE interface is my CD-RW drive, which does not detect. I do not have /dev/hd* or /dev/sr*.
| Code: | 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controller (rev 02)
Subsystem: QUANTA Computer Inc Device 0753
00:1f.2 SATA controller: Intel Corporation 82801GBM/GHM (ICH7 Family) SATA AHCI Controller (rev 02)
Subsystem: QUANTA Computer Inc Device 0753
Kernel driver in use: ahci
|
Device Drivers -> ATA/ATAPI/MFM/RLL is not set, and I have the SCSI CD-ROM, Disk, sotrage, and genereic drivers, in adition to the new SATA AHCI drivers. My sata hdd (/dev/sda) is working perfectly. I cannot for the life of me get my CD-ROM to detect. Any ideas?

| Do you have CONFIG_PATA_AMD set in your kernel? |

Hi,
I think you need to put a cd in the drive in order to get the device created, did you do that before checking?
Also, did you enable "File systems ---> CD-ROM/DVD Filesystems --->" in your kernel?

sirlark,
this should be easy. You simply don't have the right options checked in the kernel config.
This forum is full of posts that address the old libata vs pata drivers.
The easiest way to get them checked is this.
In the uppermost directory of your kernel source, enter make defconfig. Up to you if you wish to peruse the .config that it makes.. Might want to double check your file systems and processor type. Re-compile and re-post the result.
I will be most surprised if that doesn't capture all your basic hardware. If it loses something else, deal with that then.

That's the winner! Doh! I could have sworn I set that, but apparently not.
Thanks a lot.
