3.4 will boot on my desktop but not my laptop.
it just hangs when trying to detect the cdrom/sda (after it detects usb/firewire stuff)
is this because the laptop is so old? or is it because its cdrom is a moduler bay?
thanx

My Compaq/Toshiba laptops fail on the autodetect. My solution was running knoppix with the line:
knoppix26 noscsi noapic nolapic
Try the noscsi option first, the toshiba worked fine. I needed to disable the rest for the Compaq Presario 700 series.
Hope this helps

You type all cheatcodes at once.

I used the 'atapicd' option without anything else when facing this issue. This forces the use of atapi cd cddrom and doesn't try to turn it into a SCSI device.
Taken from the cheat code list:
knoppix atapicd Do NOT use SCSI-Emulation for IDE CD-Roms
The other codes posted may get you up and running but may cause other issues later on. You should try to keep options at a bare minimum to address the issues at hand.
at east thats my 2 cents

I have the exact same problem with an old Dell Latitude CPi laptop and Knoppix 3.4.
It displays...
Looking for CDROM in: /dev/scd0
...and it just hangs there.
The "atapicd" parameter fixes the problem, it's just that, with the 2.6 kernel, even with the parameter is takes a long time (so it appears to be broken regardless of the parameter).
Anyway, the 2.6 kernel fails later on with: "hdc: irq timeout"

Ok. Same thing happens with Knoppix 3.6
I wonder why SCSI emulation is still used, since it does not appear to be required anymore and it seems to cause problems?
Are there situations when ATAPI CD causes trouble?
