Digital AXPpci33 "noname" questions

I'm dusting off this old AXPpci33 motherboard of mine and ran into a few issues... I'm attempting to upgrade the firmware and I have the file from the Digital/Compaq/HP web site (Dec 2002 version), but the instructions don't match my situation. I don't have the ability to cobble up a boot floppy with OpenVMS (my DEC 4000 has no RX33 or equivalent), I don't seem to have a compatible network card to BOOTP it in, and the FAT floppy technique doesn't work with the firmware I have in there now. So... does anyone know where I can find a reference to which network cards are supported for network boot? I have all the common cards like NE2000s, 3C509s, 8013s, etc., and a few PCI cards. I even have a card in there now with a DEC 21143-PA chip, but the ROMs don't seem to like it. Alternatively, in a similar vein to what someone else recently requested for their Multia, can someone on the list make a raw disk image I can "dd" onto a blank floppy? The Unix technique on the HP webpage requires a Digital Unix binary program to convert the firmare utility file to some other format and I can't do it from Linux or Solaris. Thanks, -ethan P.S. - I also can't find any reference to the supported memory configurations of the AXPpci33 board - I have some parity 16MB SIMMs, giving me 64MB, but I'd like to use some of these parity 64MB SIMMs I have here from AIR motherboards (formerly CompuServe "CompuHosts"). Got a set of 4 ready to go, but it seems that few boards ever supported 64MB 72-pin memory. :-(
