Updating firmware for XM-6302B?

Hi, I have a Toshiba XM-6302B CD-ROM and I am wanting to update the firmware. I have searched, maybe not hard enough, for a guide on how to do it, but have come up empty. Any help would be appreciated. Thanks in advance.

Specs:
AMD 2500XP
1024MB DDR 3200
Windows XP Home (SP1)
Asus A7N8X Deluxe
