NCC10281982B Posted January 12, 2005 Posted January 12, 2005 I'm trying to boot overclockix 3.7. The comp boots up until "Looking for CDROM in: /dev/hdc" I know the cd is fine because I booted from it. I was very happy that i got that far. I used knoppix26 as my cheat code. The comp will hang at "Looking for CDROM in: /dev/hdc" and sometimes boot to a limmited prompt. The cd drive is not spinning at this point. I have beeen through this 3 times. Is these a way to fix this? Share this post Link to post Share on other sites More sharing options...
markiemrboo Posted January 12, 2005 Posted January 12, 2005 Well since that is past the kernel and on to the RC script type stuff, I would have to say it's probably either your hard disk or CD drive doesn't like being set to DMA mode. How you get around that in Linux though I don't quite know. Share this post Link to post Share on other sites More sharing options...
Zarkhalar Posted January 12, 2005 Posted January 12, 2005 Have you tried other live cd's like knoppix? I'd try one of them and see if you get the same results.. Share this post Link to post Share on other sites More sharing options...
Eva_Unit_0 Posted January 12, 2005 Posted January 12, 2005 That's weird how it sees the cdrom as /dev/hdc...most that I've seen detect it as /dev/cdrom. Anyway, I agree the problem might reside with the DMA mode. When you boot, does it give you a choice of which kernel and configuration settings to use? For example, when I boot of a gentoo livecd I can tell it not to use acpi and all that kind of stuff. Try booting with whatever flag disables dma. (I've never used that distro before, so I don't know exactly what it is) Or, you could also go into your bios and force the cdrom to use PIO mode, just for troubleshooting purposes.

LinuxGeek Posted January 21, 2005 Posted January 21, 2005 Type "linux allowcddma" at the boot prompt. It worked on my friend's Pc. If this does'nt work try "linux ide=nodma". Share this post Link to post Share on other sites More sharing options...
