Would you please all shut up about patching _HFSDispatch. Its nonsense.
If SilverLining or anyone else does so, it's for reasons that probably have
nothing to do with multiple volumes.

Also, Inside Mac does _not_ state that there may be only one HFS partition on
any SCSI device. That's a (stupid, IMHO) restriction which is enforced by the
Apple Installer and by A/UX 2.0.

PLEASE! Listen to one another!

Changing modes on a device is a function of the driver.
Alexis wasn't asking to change the driver or any other characteristic of the
hard disk, only to change the partition layout which should be an entirely
different problem. Partition layouts are standardized in IM V, right?

See above.
