Johnny, If I can not use a floppy any more to boot my server, What can I use to boot the server in case of a crash? How can I make a CD bootdisk to my CentOS Server? Is there another way to boot my server?

You could probably use the first install disk to boot into rescue mode. I have done that with CentOS-3 and it worked fine for me. I would imagine CentOS-4 would be pretty similar in that respect.

Dan,....... I know the option "linux rescue mode" works fine, but, my CentOS servers have a Software RAID (raid 1) installed and I used to make a bootdisk
in
case of a RAID failure (or a HDD crash), so, Now I can not make my bootdisk 'cause the error above...... in this case what can I use to boot my server and keep my Soft RAID working?
thanks for all your soon answers regards,
I'm confused. If your raid crashes, what good is a boot floppy (which is now totally impossible - the kernel and initrd will not fit on a floppy) in the first place? You would be looking at a rebuild of the raid and/or a restore from backup, so why not just use the CD in resucue mode as recommended? What could a floppy possibly do that the CD could not?
Please advise.
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!

I understand what you want ... but a 2.6.9 kernel and the required initrd.img to allow LVM2 and/or RAID ops is physically too big to fit on a floppy disc.
you could try to compile ONLY the drivers you absoultely need into a kernel ... but I think it will still be too large to fit.
Hi
can it be written to a cdr and just boot of that?
