Instructions for making your background image with UNIX
Kindly researched and explained by "David H."

1) Unzip the downloaded file using the 'unzip' program like this:

unzip AD1500_ABCD_R0M0.zip

( Or, if you are using the original factory firmware, the command is unzip AD1500_orig_cdr.zip )

You'll get a file named 'u1500am.rom'.

2) Make an ISO9660, type 1 image file containing the u1500am.rom file using the 'mkisofs' program like this:

mkisofs -iso-level 1 -o apex.iso u1500am.rom

Note that the '-o' option is where you name the output of mkisofs. Here, the output file is named 'apex.iso'

3) Burn a CD-R using the ISO image file you made in step 2 with the 'cdrecord' program like this:

cdrecord -v speed=2 dev=0,0 apex.iso

Note how we used the 'apex.iso' image file name at the end of the command line. Your 'speed' and 'dev=' numbers can (and probably will) be different from the above. For speed, consult your CD burner documentation. To get the dev= number, run cdrecord like this:

cdrecord --scanbus

and look in the output for your CD burner hardware. The cdrecord manpage is also quite useful.
