MB rather than k?
I installed Suse on a PC with 80 MB RAM. Text/command line only. Same problem.
I got my Debian Woody rescue and root floppies.
Do just enough to get to the menu and choose partition a hard drive. You can use cfdisk to create a swap partition from free space. (You know not to try to resize partitions with cfdisk, right?)
After creating the swap partition you then need to choose initialize and activate a swap partition.
After that Suse can use the swap partition during install.
Yast (ncurses version) will run but it will be as slow molasses. Some functions take 5-10 minutes or longer.
Even in text mode, Suse is not a good choice for a low RAM PC.
Another choice is to put Zipslack on your Windows 98 partition. It is command line only but you can add Slackware packages to it.
