Need help w/ ATAPI cd-rw drive

hey. i have a cendyne cd-rw drive model no CW 4001. i found the manufacturer on google and it was MSI. they have the latest firmware version but i don’t know how to install it. i have windows xp pro and i tried booting in DOS mode but it doesn’t show up when i press F8. the firmware version is 100c and i’m trying to update it to 120d because i can’t burn a cd at any speed. it always said “no seek complete” when using nero. can anyone help me install the latest firmware version?

You need to use a boot disk to get into DOS.
