Code:
boot:sata.i root=/dev/sdaN
this is what i've used before, if you're using not-sata devices then pick a different kernel, probably huge26.s, and your 'root=' should point to some hdXN partition, where X=a-c and N=1-? i.e.
Code:
boot:huge26.s root=/dev/hda1
above would work if you're using ide drive primary master, and the first partition is where your root fs resides.
indeed, if this works you should not have to chroot.
you'll then ? need to make sure that you can find the CD you booted off, then look in /dev/cdrom/slackware/ for glibc
sorry, not sure which directory thats in.
*note, if you have /usr, /home or other base filesystems on other partitions it would be good (required?) to mount these as well
before trying to installpkg.
*note- you may have to fully specifiy the path to installpkg (i think its just /sbin/installpkg but could be /usr/... somewhere)
