[comp.sys.ti.explorer] How do I boot from a disk with a corrupted label?

norvig@COGSCI.BERKELEY.EDU (Peter Norvig) (06/27/89)

I got an error while running edit-disk-label, and as a
result, I can no longer boot my machine: I get 

DEVICE ERROR: DEFAULT MICROLOAD NOT FOUND

for either a D or M boot.

How can I get this disk reformatted properly?  I have other
working Explorers and an ethernet available.

Much thanks,
