DVD Firmware upgrade

[Guest]

After several windows updates the dvdrom beguins erratic (not always working)
readings of audio and cdrom cd until the last update that only reads
COMMERCIAL dvd's and NOT recorded by myself.
I believe a firmware update should fix the problem.
As I have have a compaq presario notebook that supports only a dvd or
diskette drive at one time. How can I update the dvd rom firmware as I can't
use the diskette drive at the same time as the dvd rome drive? The firmware I
have can't be executed from windows. It should be using a bootable diskette.
Besides the pc bios doesn't support booting from external USB drive which
could be an option.
I have a Question: Can I use a FAT partion on my HD that contains the
firmware
upgrade and boot it using PQBOOTX.EXE included in Partition Magic?
Please help.
Thank you
I'm using Windows XP SP2, DVD-rom: LG DRN8080B (reader only)

Hi RoadRunner!
I had downloaded the firmware upgrade from the internet and made a bootable
diskette following the corresponding instructions and afterwords moved it to
fat partition on my hd for further processing if it is possible to do it.
That is why I'm asking if I can boot using Partitions Magic booting software
PQBootx.exe in order to upgrade the firmware when my DVDrom drive is
inserted in my laptop.
