How to update CD Firmware on laptop

I found a firmware update for my T40's DVD/CDRW drive. It requires the use of a floppy drive, but the T40 does not come with one. The Firmware update won't detect the drive under Windows for some reason, but it does under a pure MS-DOS environment (I booted from a MSDOS bootable cd and ran the utility but can't run a firmware upgrade for a drive while reading off the drive). Is there anyway to attact a desktop floppy drive to this or any other way to make this firmware update work?
 
What about a RAMdrive? I think the Win98SE bootdisk used a RAMdrive; maybe you could make that into a bootable CD (get bootdisk from Boodisk.com), and transfer the flash files to the RAMdrive and flash from there.
 
I think the RamDrive is writeprotected from the Win98SE bootdisk. Can I make a bootdisk and create my own RamDrive at A: to emulate a floppy?
 
Didn't know it was write protected; I just knew it existed.
I'm checking my files, I did at one time have a DOS-based, commandline RAMdisk utility. You'll need himem.sys on the floppy drive, and add devicehigh=himem.sys to the config.sys on the bootdisk if it's not already there.
This utility is very small, and effective. I'll post a link here when/if I find it.
 
Good question...I would think not though, as the drivers and OS should be loaded into the system RAM. The files it needs (flash utility and ROM/BIN file) should be stashed in the RAMdrive, and be accessible from there.
Anyone else have advice on this? This is theory on my part - it sounds like it should work; I don't see why it wouldn't. It really should though.

Link - XMS/EMS RAMdisk.
 
The problem I keep encountering is that every way I can think to load DOS makes it dependent on my CD-Rom drive. I can make a DOS bootable CD, but all the commands are run from the CD. Ideally, I think I need to create a RAMdisk, load all the files into that, then free the CD drive. The Win98SE ramdisk example is what I'm looking for, but it keeps the RAMDisk write protected. If there was a way to undo that, it would work. So if anyone knows of a way to load DOS completely into a RAMDisk or load DOS from an NTFS partition, it would work.
