Your are correct in that the drive is recognized in cable order. Also you can use the system set-up utility (F2 at boot time) to tell it which drive to boot from, but don't forget to set the jumpers on the second drive to the slave settings (instructions usually on the drive itself)

Also if you have partion magic you should be able to run from the boot disks.

I would remove the WIN98 if the primary drive has XP.

I found an easier solution from a query in another forum.  There's a program called Casper XP that copies a partition to another drive.  I copied the C drive from my 20 gb drive to my spare 60 gb drive, removed the 20 gb drive and connected the 60 gb drive to the connector at the end of the ribbon cable.  The 60 gb now serves as my only drive, and works fine. I tried the cable select jumper instead of slave when copying, and it worked ok.  The 20 gb drive is now my backup, replacing the missing cd's (wish I had the CD's, but that's life).

I connected the 60 gb drive to another computer and used Partition magic to change the C partition to an extended partition to avoid any possible problems, but don't know if it was really needed.
