[ltp] T23: Booting with different Ultrabay devices

Does anyone know how to get Linux (I have Redhat 8.0) to boot without having
to tell it in advance what's in the UltraBay?

I have a second hard disk with a Linux partition on it, as well as a CD-ROM
drive. The CD requires hdc=ide-scsi on the kernel command line; the hard
disk requires this parameter to be absent. 

If I boot with the ide-scsi option and the 2nd hard drive is present
instead, the hard drive is not seen. 

So I have grub set up with two different boots to the same kernel, with and
without the command line parameters, and I have to shutdown and reboot to
change devices.

Of course, this also prevents me from easily mounting and dismounting to
hot-switch the devices, as the kernel support is incorrect for one or the
other device.

Any suggestions?
