This is the procedure for creating a bootable floppy:

Procedure for creating a bootable SunOS floppy diskette.

                   1. Insert floppy in Diskette Drive.
                   2. newfs /dev/rfd0c
                   3. mount /dev/fd0 /mnt
                   4. cp /usr/mdec/bootfd /mnt/bootfd
                   5. cp /usr/kvm/stand/boot.sun4c /mnt/boot
                   6. /usr/mdec/installboot /mnt/boot bootfd /dev/rfd0c
                   7. Copy your vmunix kernel to the floppy.

                 Note: There will only be ~950K remaining so the vmunix
                       will have to be very small.
     
                 Here is a sample installation session:

                 \# newfs /dev/rfd0c
                 /dev/rfd0c: 2880 sectors in 80cylinders of 2 tracks,
                             18 sectors
                 1.5MB in 5 cyl groups \(16 c/g, 0.29MB/g, 128 i/g\)
                 super-block backups \(for fsck -b \#\) at:
                 32, 640, 1184, 1792, 2336,

          \# mount /dev/fd0 /mnt

                 \# cp /usr/mdec/bootfd /mnt

                 \# cp /usr/kvm/stand/boot.sun4c /mnt/boot

                 \# installboot -v /mnt/boot bootfd /dev/rfd0c
                 Primary boot: bootfd
                 Secondary boot: /mnt/boot
                 Boot device: /dev/rfd0c
                 Bootblock will contain a.out header
                 Boot size: 0x1af40
                 Boot checksum: 0xf22db98e
Boot block installed

                 \# ls /mnt
                 boot        bootfd      lost\+found

I doubt if you could put all this into some file, ftp it to the p.c., and then put it on the floppy. The problem I see is the newfs command and the installboot command. How to create the floppy
with this... And then how to use it even if you did create it since the SUN system does not have a floppy.

thax rtm , i knew above procudure , but was doubtfull only of sending it across ftp , as u also mentioned.
thanx any way.

You do realize you can boot off the cdrom drive into single user and work on your drives, or boot cdrom and install. If you are looking for different ways to be able to get the server up and running (after a problem). Also check out jumpstart.

The OS cd tht came with system , works fine , but when i say boot cdrom from ok prompt , it says boot failure .
any way i dont have problem yet with system , os is running fine, i waj just trying this. thanx
