--I have to do this for my "fast" system (AMD 900MHz Duron with 196(608?) KB of Ram:

boot: ' knoppix mem=190M ' == Make sure you cap the M

--The reason for it is that the Knoppix boot process can't autodetect the proper amount of RAM that's installed on the machine when it tries to boot. HD-installed Linux (including Knoppix!) works fine w/o any boot switches. (shrug) Only happens on that one machine. Klaus mentioned something a long time ago about certain motherboards / chipsets having this issue; I just passed on the workaround. Post results.

#2 "Kernel panic: VFS: Unable to mount roof fs on 01:01"

And then the boot hangs there forever (well, probably; obviously I haven't actually left it quite that long!)

Does anyone know what the problem might be and if there's a way to get around it? Any suggestions gratefully very received.


I'm running an AMD Athlon 1600 with 512Mb RAM and 40G HDD, if that's any help.
