the prime driver wasn't CD-ROM I think , it is nonsence ! Haha
Hei question-master ? have you the booting floppy? change the prime driver to floppy, and use some booting floppy to boot your machine, and step by step .
of course , you can use WIN98 CD to boot it , repair your "mbr" , then reboot and load your LINUX CD and turn into "rescue mode " .
