Collins,
Most of my servers are connected remotely, I migrated from WhiteBox to CentOS
linux, I had in every (remote) server a bootdisk (floppy), so in case of a raid
crash, some people there booted the server from the bootdisk and then I
reconstructed the Raid remotely...
I know if I boot from CD rescue mode I can get the same result, but, people in
thouse places are not especialized in linux boxes. That is because I want to
boot from a floopy, now I also know it's imposible, but, Can I make a CD boot?,
I just want something to boot my remote server, get running all services and
later I reconstruct the RAID...
understand me now?
sorry my poor english!
regards,
israel
