I've been stuck at home with a cold during the week(end), so I've been fooling around a bit with a National Semiconductor SC2200 based system. It has taken me a couple of days to get the chipset setup and ram sizing working, but now it can boot a Linux kernel from flash.
The PCI bus with two NatSemi DP8315 ethernet chips on it works, the built in IDE and USB controllers also work. The built in serial ports, ACCESS.bus controller, watchdog and RTC also work. I have not looked at graphics or sound at all and getting that working will probably be a lot of work.
Is anybody else using a SC1200, SC2200 or SC3200 based system and interested in getting LinuxBIOS running on that system? I'd be happy to share what I have now, but it does need to be cleaned up a bit first. There are a lot of more things that could be done too, such as optimizing the memory, there are at least another 256k of RAM that could be given to the Linux kernel, and of course there's graphics and sound to work on.
I've seen a few messages regarding getting Grub/Etherboot/Tiara running instead of linuxbiosmain. Has anybody done work in that direction? What I would like to do is to use grub to boot from a local hard drive/Compact Flash, or Etherboot to boot over network using a NatSemi DP83815 ethernet controller.
