Hi, well Firmware is a broad term - let me split it up into two cases:
1) boot <installer> from CD or FTP server (e.g. 'Load from Removeable Media and Server' task),
   then install to disk and reboot from that disk - possible in classic HMC mode and DPM
2) boot <installer> from network server (PXE-like), then install to disk and reboot from that disk
   afaik DPM mode only

Obviously both requires firmware support - but probably different components.

The MAC address should not change (in the above examples) between the 1st boot (e.g. installer) and the 2nd (re-)boot (e.g. a post-install restart of the system from disk).

Having MAAS in mind we particularly require the 2nd case (network-booting an LPAR in DPM, installing to disk and restarting from that disk and always having the same unique MAC address).
