Most of the information I have placed here so far was gleaned from the Linux/MIPS homepage. The URL for that site is http://www.linux-mips.org.

MIPS Architecture Stuff

Here is a history of the MIPS Magnum series and how various derivative boards came about. It was written by Ralf Baechle. MIPS Magnum History There should also be information on how to configure the Magnum's firmware here soon.

Hardware Compatibility

Now the bad news: The MIPS Magnum series requires a proprietary $315 128-bit video card that will only work with the MIPS Magnum. NO OTHER VIDEO CARD WILL WORK. This rules out using an ISA or EISA video card.

What's worse, neither availible operating system (Windows NT and Linux) allow booting without a video card, so we are stuck with the cost of the card.

I have heard accounts from people that the PROM for Risc/OS supports a serial console mode. However, AFAIK Linux can't use the Risc/OS boot console (yet). I have no experience with Risc/OS, but I do know that it is at least 4 years old and that no development has taken place in that time. So if you can find a copy of Risc/OS, I would appreciate hearing what worked for you and what you had problems with.

For Linux, you will need to load the little-endian firmware originally designed for Risc/OS. Check the Linux/MIPS homepage for the firmware update disk.

The MIPS Magnum requires at least four and at most eight true-parity 72-pin SIMMs to operate. Fill the slanted memory slots under the drive bays first. Its maximum memory is 256 megabytes, but if you max the memory you will need to reduce its clock speed from 50mhz to 40mhz.

Here is the info for Carrera Computers, the company that bought the rights to and resells the MIPS Magnum video cards.

Ask for Ryan, the sales representative I spoke to. He seems to know the most about this card.

As for other EISA/ISA boards that might work with the Magnum, I have no idea as I haven't received my board yet. If anyone else knows if a certain peripheral works or doesn't work with the Magnum, please leave me an e-mail specifying the name and type of board.
