I have sad news. You can't get a 4 MB chip on that board, I bet.
I can't get to this. This means that 4 MB Flash ROM cannot be used with SC1200? Or is it not supported in LinuxBIOS. Plz help me to understand these.
It is probably 4 Mbits, 512 KB. You'll have to put that overweight linux kernel on a diet to get it to fit in there.
One option is 2.4.0 or so, that might fit.
Can DoC fit on your geode anywhere?
No I don't use DiskOnChip.
Thanks.

The SC1200 can address up to 16MB of memory on the ISA bus (which is where the Flash Rom would be located for the BIOS if strapped for ISA BIOS ROM seek after reset) or it can use the LPC bus (if strapped for LPC BIOS ROM seek after reset). This is what the SC1200 is capable of if you're designing your own board. It's just unlikely that if you're using an off the shelf board that it will support >2MB of flash ROM on ISA. If it uses an LPC ROM then it's probably soldered down and a 2MB device. LinuxBIOS can support a 4MB device or up to a 4GB flash ROM (if they actually existed).

Sorry about the typos. (MB megabyte vs Mb megabit) That last sentence should be:

it means that you said "4 MB" which is a common mistake. If you send me the part # of flash I will bet it is actually 4Mbits (i.e. 4 Mb)
you can't put linux kernel in 4Mbits any more.

Sorry mine is TE28F320C3TC70 (Intel) 32Mbit Flash memory. If I have to boot from Flash memory what part of linux bios should I concentrate? What changes has to be done?
Thanks.

NEAT!
removeable or soldered on?

It is a soldered one.

So is the question how you program it? Is there a recovery jumper for when you burn a bad BIOS? Can you send me the URL for the board?

Hi,
Sorry if my question sounds stupid. How would LinuxBIOS know that it has to boot from Flash memory. Is something has to be mentioned in the nano.config file?
