I've been digging through the internet trying to accommodate a need I have to install CentOS (5.4) on a machine with the following configuration:
IDE0:0 Compact Flash (128MB card)
SBA: USB mass-storage device (1GB or so)
RAM: 512MB (however, trying to AVOID ISO loading into memory)
What I "want" to do is have the CF boot the machine and tend to HAL... but have the actual "OS" on the USB drive (which could also be used for swap if needed) however I have yet to find a way to accomplish this.
How to format the CF to manage GRUB, etc. and then switch over to sba: for the actual operating system. I have running Windows and Linux machines at my disposal to accomplish the task.
In the end, what I'd like to end up with is a flash drive that holds an OS that the CF "calls onto" thus allowing somewhat of a plug-n-play environment where the OS could be switched out without having to do much of anything to the /boot (CF)
Thoughts and/or ideas welcome!
