mkisofs to make bios update cd from floppy image
 

Hi, I have a question that I havn't been able to solve despite a lot of
searching and messing around.
I have a Thinkpad 600 with no OS so I want to install Slackware. But
every time I put in the slackware disk i get an error: ISOLINUX 2.13
2004-12-14 isolinux: 0142E58B
What I think I need to do is a bios update.
So I download the bios update and it's one of those executables that
makes the boot floppy. So I run that on windows and get the boot
floppy. However, there is no floppy drive on the Thinkpad (you'd think
IBM would know this).
So I went back to linux, and copied the floppy image to a file.
Now I need a way to somehow get this floppy image on a cd.
So I installed mkisofs and ran:

[root@localhost matthew]# mkisofs -pad -b /home/biosUpdate2.img -R -o
/home/biosUpdate2.iso /home/biosUpdate2.img
Error creating boot catalog, exiting...
Not a directory
[root@localhost matthew]#

where /home/biosUpdate2.img is the floppy image.

I've been through all kinds of manpages but cant seem to find an answer
to this one.

Any help is appreciated.

Never mind I got it.
