know how to set the MAC address?  I have RiscOS running on that machine if

It appears my RC3230 is the same :(

To make matters worse, I have no way of actually booting my RC3230 as the
disks in the system appear to have either been corrupted or erased, and I
have no RISCOS tapes. [The machine was a gift from an ex-hacker who got it
through unknown means].  This prevents me from actually using the machine.
Anybody willing to send me a QIC150 cartridge with an appropriate install
image, and basic install instructructions, would be greatly appreciated at
this point :)

Just make it a boot parameter...  I could live with that.

Do any of the Sparcs use this nvram chip?  I fortunately have access to a
large number of SparcStations.
