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
2. Choose option 2: 'create emergency boot and root floppies.'
3. Choose the appropriate floppy type.
4. Choose to create the Root floppy.
5. 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.
