That is something, I honestly don't know. I've asked on the debian-alpha mailing-list first and did not get any explanatory response. I've checked the card in a x86-machine ( just to very it's working and to configure RAID drives ). In this machine, the card posts a banner, saying it's a Mylex and - depending on the BIOS enable/disable setting - posting some keypress options to start the build-in firmware. That i don't see on my alpha, which does not necessarily mean something.
The SRM firmware contains a small x86-emulator, being capable to at least run the POST-routines of normal PCI cards. AFAIK, this emulator works on a lot of cards, but is not capable of doing any screen/terminal I/O. For example, if you use Matrox vga cards ( quite common on alphas ) you get a working grafics device, but yoy won't see any matrox banner on the screen. Newer firmware's even support a "run_bios" command, that allows to start configuration routines, like the RAID setup. Unfortunately, a version of this newer firmware does not exist for my machine.
Mylex OEM'd some earlier DAC-models to DEC for use as a RAID controller. These came with their own firmwaer, which allowed ppl to setup logical RAID-drives. I can't tell, if the firmware handles any other POST stuff.
The controller comes with a SA-110 processor running it's own firmware. I would assume, that the SA-110 handles POST - but that's honestly just a wild guess.
