I just got a floppy drive and a floppy disk for my laptop to do this for your sake (and mine) so I hope it works and I hope you feel special because I normally don't get to do this. I used AUTOQSI2 from the link posted by babychar2002 on a boot floppy and dumped the firmware in BIN format using MTKFLASH.
I'm not sure how successful this will be, but I figured using MTKFLASH to write it back to the drive would be alright. Don't blame me if the drive dies or anything. Use your own judgement. And I think it might be safer to use the AUTOQSI package from the link given by babychar2002 (http://etna.rpc1.org/qsi/) and follow the instructions to make your own boot disk to flash it.
To flash a drive:
MTKFLASH "x" W /B filename.bin
Where "x" is a number from 1 to 4:
1: Primary master
2: Primary slave
3: Secondary master
4: Secondary slave
W is to write a firmware to the flashrom.
/B is to tell the program that the input file is a binary file.
filename.bin is just an example. Write the name of your firmware file here.

When you download, there is two parts. Remove the .zip at the end because it is a two part rar file (due to forum storage and filesize limitations). Then unrar. Winrar can be found at www.rarlabs.com
This is the firmware that came with the SBW-242B that's in my Excel/Clevo D410J Laptop. It is able to write CD-RW at 24x (not 10x as earlier firmwares) and I think this might be the latest on the net (as I put it up as of now).
I have also attached a screenshot just to show you the drive ID and capabilities in action.
