I set up the two disks separately one at a time as the master disk. 
Then I made my Win98 disk the slave with the jumper and plugged them
both in.  This is what I found to work in grub for Win98:

title win98
	map (hd0) (hd1)
	map (hd1) (hd0)
	rootnoverify (hd1,0)
	chainloader +1 

There is lots of examples on the web, you may just need to find the one
that works for you and your OS.
