General Support - ALi15x3 chipset IDE support

Titel: ALi15x3 chipset IDE support

I have a Thinkpad i1300 laptop, which uses the buggy ALi 15x3 IDE chipset. (I discovered this fact after I got it.) I've been trying to find a Linux distribution that works properly on it. I got it working once with Gentoo, but the machine's too short of RAM to really be viable for Gentoo; any non-trivial emerge takes all day as the machine thrashes. (I can't add more RAM; there's only one slot and it's already maxed out.)

Anyway, the thing is, I found that Knoppix 5.1.1 mostly Just Works, except for the TrackPoint mouse (which is correctly identified at boot but doesn't work at the Knoppix desktop), and handles the ALi15x3 chipset just fine. But, it says "Don't install it on hard disk." So I'm trying Kanotix, which is intended for hard disk install.
There's just one problem: The Kanotix CD's kernel does not properly handle the ALi15x3 chipset, and consequently cannot access the CD drive once the kernel is booted. (The error:
ide-cd: cmd 0x5a timed out
hdc: lost interrupt
at which point booting stalls as the kernel retries and retries and retries the CD forever.)

Whatever you did with the kernel on Knoppix 5.1.1 to support the ALi15x3 chipset, can you do it on Kanotix 2007 as well? I'd love to try Kanotix on this annoying laptop, but I can't try it if I can't finish booting it.

I'm currently appending the following options: nousb dma acpi=force ide0=ata33 ide1=ata33 ide2=ata33 ide3=ata33. The ide options are to try to help work around the buggy IDE chipset; the nousb is to work around the laptop's buggy OHCI USB controller, which hard-locks the entire machine if probed at boot.

(Yes, I'm beginning to hate this laptop.)

Zitat:

If the hard drive is accessible, you could copy the iso file to the hard drive and use cheat code fromiso=K*.iso to bypass the CD drive.

Thanks for the suggestion. I'll give that a try.
