im assuming that your drive is IDE, cause u havent mentioned otherwise..
anyway , for ide, the usual format is /dev/hda(x)
im not sure how its done in suse...but the swap file is usually placed before the root drive...so im guessing..
/dev/hda1/ = swap
/dev/hda2/ = root
Doesnt the suse rescue disk have some sort of partition manager? u can get a look at which drive is swap thru that...if u have windows installed, then this is probably it..
/dev/hda1/ = windows
/dev/hda2/ = swap
/dev/hda3/ = root
basicaly trial and error.. oh and if ure drive is SCSI, the 'hda' becomes 'sda', and if ure boot device is the second drive(slave), then its /dev/hdb
