[expert] Boot Trouble

[DuBose8]

Hello

I installed another flavor of Linux, and now cannot get back into Mandrake. 
I've booting into it from floppy, but the partition table has changed. I need 
to tell it at the boot prompt that the boot part is at hda5 instead of hda6 
now, how can I do this if its possible? Unfortunately I don't have a rescue 
disk.

Thanks
Scott
