Does this mean that my system comes up with the exact value co-incidentally? Or does this mean that mkbootdisk always tries to make the image reflect the size of a floppy? Would a larger than 1474560 vmlinuz and initrd fail or cut off the end of the file, post 1474560?
The image will be exactly floppy size even if it is not completely full. You can change the size with the --size option. Take a look at
# man mkbootdisk
This option I noticed while reading the man page for mkbotdisk. I assumed the default would be for a 1.44 (or 1474560 :-) ) floppy.

1203768 + 190569 = 1394337
I did the below command and ended up with a larger image.
I burned the disk with the newer iso image, in order to see what was on the disk. This had the /isolinux directory and the trans.tbl file.
As an aside, you don't have to burn these images to see what is inside them. You can mount them using the "loopback" interface. Here is an example:
# mount /tmp/testboot.iso /mnt/cdrom -oloop
This would mount the image just like it was burned and sitting in the cdrom drive.
Good pointer.
I tried this command and it worked like a charm. It even added an icon on the desktop for the loop mount.
I am glad that I wasted a disc (given to me anyway) to make the CDR with the below options. I booted with the burned image and found that I lost my tapping feature for my laptop. I assume that you would have to type in the magic incantation during boot to get tapping to work, when booting from iso or floppy.
mkbootdisk 2.6.6-1.435 --iso --device /tmp/testboot.iso
Size of boot image is 4 sectors -> No emulation [root@jcsevern root]# ls -la /tmp/testboot.iso -rw-r--r-- 1 root root 1794048 Jun 19 00:00 /tmp/testboot.iso
Now I have a boot iso! I don't have a built in floppy on this laptop.
Thanks!
