Sorry about the bogus time stamps on my previous mails...
Ok, problem averted. After searching a bit I found the following web page
for help:
http://developer.apple.com/techpubs/hardware/DeviceManagers/pci_srvcs/pci_ca
rds_drivers/PCI_BOOK.5e.html#13748
Which helped me learn to do the printenv command from open firmware.
Doing so showed me that my environment tables were corrupt- probably due to
using TechTool 1.2.1 (let this be a lesson to us all :-) After this I did a
reboot with PRAM zap twice in a row. This seemed to restore the environment
to the default, allowing me to set the bootscript again as the boot-device.
Anyone know where I can get a complete manual on open firmware commands?
