Q. I need to create a boot floppy from Solaris DVD image. How do I create a floppy under another Solaris box? Is it possible to create a boot disk under Linux?
A. You can create a boot floppy using image called d1_image located under Solaris_10/Tools DVD/CD directory.
You need to use dd command to write to floppy disk. Use fdformat to format floppy diskette.
You must login as the root user.
Step #1: Insert floppy disk and type the command
Run volcheck to mount floppy
Format the disk (if required):
# fdformat -d -U
Step #2: Insert Solaris DVD/CD
Run volcheck to mount DVD/CD
Step #3: Copy disk image to floppy
Copy image to the floppy disk
# dd if=/cdrom/cdrom0/Solaris_10/Tools/d1_image of=/vol/dev/aliases/floppy0 bs=36k
Step #4: Unmount both floppy and DVD/CD
# eject cdrom
# eject floppy
Create a boot floppy in Linux
If you copy /cdrom/cdrom0/Solaris_10/Tools/d1_image file to Linux system you can use dd command itself again:
# dd if=d1_image of=/dev/fd0 bs=36k
