Bootable disk

UNIX for Advanced & Expert Users
1

I have a SCO Openserver 5.0.6 running Raid 5. and want to make a bootable disk but the boot image is 5MB ie unix file on root is around 5M and the size is obviously too large for a floppy diskette. Please help on how I can make any bootable device. The aim is to change the filesystem size.

Thanks

cant u do that on tape?

I don't know how that is possible on tape. Because i guessed tape is not part of the bootable devices.

You should be able to boot single user off of the cdrom (installation cd). Check your documentation (if you don't have any then go to www.sco.com for it).

Hi,
The SCO server has a 16-port digi board on ISA board, a 4-port digi channel on PCI board, a 50-pin scsi adaptor. These are the configuration and booting from cdrom would be like doing a reinstallation if I'll need to reconfigure the digichannels and sna (this I want to avoid if possible).
I guessed this has made the sco cd redundant in this regard, unless a reinstallation.
If the boot image cannot go on floppy, is there a way I can make a bootable cd with the present system state.

thanks.
Sola

Have you attempted to make a boot/root floppy?

Found on caldera support page:

Description:

With rs506a installed on your system, booting the system up from
boot/root floppies on Openserver 5.0.6, cpio fails to work. It will
fail with:

dynamic linker : cpio : error opening /usr/lib/libsocket.so.2
Killed

NOTES: This problem only arises with rs506a installed, this is important
for the two libraries needed are not on the base install of OpenServer
5.0.6.

CAUSE: The following two libraries have not been put on the root floppy
when mkdev fd is run:

/usr/lib/libsocket.so.2
/usr/lib/libresolv.so.1

Solution:

This problem has been submitted to SCO engineering.

A workaround, for now, is to put these two libraries on the root
floppy disk.

  1. When creating the root floppy, you will be asked if you
    wish to put additional files on the disk. Enter "y" and type
    in the two libraries:

# mkdev fd

  1. Choose option 2: 'create emergency boot and root floppies.'
  2. Choose the appropriate floppy type.
  3. Choose to create the Root floppy.
  4. Enter "y" when prompted with the following:

'Do you want to place extra files on the root
filesystem? (y/n)'

You will now need to copy the two libraries to /mnt where
the RAM disk image will be built later:

<bootroot> cp /usr/lib/libsocket.so.2 /mnt/usr/lib/libsocket.so.2
<bootroot> cp /usr/lib/libresolv.so.1 /mnt/usr/lib/libresolv.so.1

Now finish creating the root floppy disk and cpio will work after
booting off the emergency floppies.

Try this link - it may help.

I'd take a look at a product called BackupEdge/RecoverEdge from Microlite corportation. www.microlite.com
