Presumably your tomsrtbt-1.7.361.ElTorito.288.img file just needs to be
burned onto a cd using cdrecord. mkisofs is for making your own .img
file.

Here is the 'cheat sheet' I use for dealing with making cds. I just cat
this file and then cut-n-paste. Note, the specific file name 'image.raw'
can be anything you want. The first cdrecord is for CD-R and the second
for CD-RW. You may need to adjust the speed and dev parameters for your
system.


#burn cd image
cdrecord -v speed=8 dev=0,0 /tmp/image.raw
cdrecord -v blank=fast speed=8 dev=0,0 /tmp/image.raw

# with Rock Ridge extentions (for unix use only)
mkisofs -R -o /tmp/image.raw .

# with Joliet extentions (for windows use)
mkisofs -J -l -o /tmp/image.raw .

# mount image for testing (must be done as root)
mount /tmp/image.raw -r -t iso9660 -o loop /cdrom

# compare mounted image with original
(for i in *; do cmp -l "$i" "/cdrom/$i"; echo $? $i; done)|less
(for i in */*; do cmp -l "$i" "/cdrom/$i"; echo $? $i; done)|less

# all-in-one
mkisofs -R /master/tree | cdrecord -v speed=8 dev=0,0 -
