ok, probably my error, but this is what I tried:

login to console per your directions as root
execute /etc/init.d/kdm stop (that halted X)

inserted cdrom, mount /cdrom cd /cdrom/drivers (this is where shell script resides) also tried copying to /usr/src/linux (same return after switching directories

export CC=/usr/bin/gcc-2.95
ll /usr/src/linux returns lrwxrwxrwx 1 knoppix knoppix 12 Jan 22 19:27 /usr/src/linux -> linux-2.4.22

same return for export IGNORE_CC_MISMATCH=1

tried running sh install script

not getting /usr/src/linux pointing to /usr/src/kernel-headers-2.4.22-xfs./nvidia_installer in order to choose compile custom module

sh script fails
