Bootable CD ROM Bigger Than 2.88MB?

[Kenneth Loafman]

I need to flash the BIOS on my Dell Inspiron 1501 and also apply a 
firmware update to the DVD writer.  I've been searching, but have not 
been able to find a way to build a CD ROM over 2.88MB in usable size. 
That means that the 3MB exe's that Dell supplies just will not fit.

I've ruled out bootdisk.com and a bunch of others due to this serious 
limitation.  Somewhere there has to be a site that explains how to build 
a bootable CD without limiting it to floppy size.  Or is there?  I just 
need to be able to put about 7MB on the CD, some for the msdos system, 
and the rest for the two exe's.

And no, I do not dual boot.  Strictly Linux, mainly Ubuntu.
