boot to usb hard disk

**[email protected]** · June 12th 07, 02:55 PM posted to comp.sys.ibm.pc.hardware.storage

I know this can be done - but haven't been able to figure it out.

I want to boot off an external USB hard disk (Iomega Ion drive) - and
load Ghost images. The system BIOS supports booting from a USB device
(it seems it - but I need to fdisk the drive so that it is bootable).

I am able to load the USB driver on a DOS boot disk - but fdisk
doesn't work - it says "unable to access" the drive.

I'm using the Panasonic USB driver with the following config.sys

DOS=HIGH,UMB
LASTDRIVE=Z
DEVICE=HIMEM.SYS /testmem

ff
DEVICE=usbaspi.sys /v /e

Any suggestions would be appreciated.

Regards, Jerry Kimball

You just want to fdisk the external drive? Why not do it with
Windows or Linux?

That USB driver is only for CD drives. You shouldn't need any driver.
Does the BIOS recognize the USB drive during POST?
