I you hunt around, you might find a reference called "Writing FCode 2.x
Programs". If you can't be bothered to hunt around, go to:
download the PDF, and then, on page 83, there is an example of setting/adding
the `local-mac-address' property. You will need to type something like:
ok setenv local-mac-address? true
ok cd /iommu/sbus/SUNW,hme
ok " "(08,00,20,00,01,ea)" xdrbytes " local-mac-address" attribute
Replace the device path with the correct device for your machine (the `ls'
and/or `show-devs' commands will be useful here). Yes, all the " characters
and spaces are correct on the last line. Pick your own "unique" MAC address.
The above won't survive a reset. I thought something like:
" /iommu/sbus/SUNW,hme" select-dev
" "(08,00,20,00,01,ea)" xdrbytes " local-mac-address" attribute
added to the nvramrc would work, but this causes a long (60 second) pause
on reset and the kernel thinks there is a second QEC card, so fails to boot.
Adding something to src/sys/arch/sparc/stand/boot/prompatch.c might well
work, although it wouldn't be very portable.
