Quoting Steve Spano steve@fl-eng.com:
Hello folks,
We have developed - basically a clone of the DB800 Amd Geode LX800 reference system.
We have an LX800, CS5536, SST04 LPC Flash (512KB) and a compact flash card - 1GB.
The system is booting Ubuntu 6.10 using a commercial BIOS.
I have downloaded the corebios and wish to get it running on our board. I have been able to download it, configured with FILO and its almost working.
What I want it to do is boot into the GRUB sector of the compact flash card and then allow grub to let me select what linux kernel/etc to boot.
When corebios loads FILO, filo says "mounting FAT" and it cannot find our grub sectors/etc on the compact flash card. Shouldn't this be EXT2 that it mounts.
Can you confirm this is was partitioned as ext2?
I have adjusted the configs for FILO to attempt to remove FAT, but it still keeps coming up. Seems like I a missing something pretty simple.
Maybe the MBR on your CF card has a fat partition entry on it? you can try wiping the mbr with dd: dd if=/dev/zero of=/dev/hda bs=512 count=1 But be warned dd can be dangerous so be careful.
Can anyone point me to a reference on how to configure the latest corebios/FILO package to boot into an IDE compact flash (the compact flash card is right on the IDE bus of the CS5536).
Doesn't it just show up as a drive?
Also - doesn't have to be FILO. I saw etherboot can boot to IDE as well. I just want a BIOS so I can alter the memory timings/etc and jump to my compact flash card for booting. So whatever is easiest.
Etherboot works too, but only upto version 5.2.6
Hope that helps.
Thanks - Joe
