I've found a box with label MIPS Millennium 4000SC-50 which I identify
as a Magnum computer. It has EISA slots, onboard Sonic Ethernet card and
a SCSI controller (plus audio channels but it's not so interested for
me). The box has RISC/os installed and operates in big endian mode.
I am interesting in having Linux in it running in big endian mode also.
Certainly, I would like to spend some efforts and port Linux if nobody
has done such a port. (I know Linux runs on Magnum in little endian
mode, nut I am not sure there is a port with big endiean one.)
So, could anybody explain how to boot the box over network (best case)
or from a floppy? Also, are there programmer's manulas for this box,
especially its interrupt controller, Sonic Ethernet card, and a SCSI
controller. Sorry, I don't know what SCSI controller is installed
onboard, but I think there should be only one for all Magnums. :-)
