Subject: [fb-d] NatSemi SC2200
Hi,
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.
Another thing, and this might be anathema on this list *grin*, do you
know what Windows CE needs to be able to boot, could it be persuaded
to boot from LinuxBIOS do you think? How hard would it be?
