Probs with flashing my toshiba sd-m 1712

I want to flash my Toshiba SD-M1712 with the 1004 firmware that remove the dvd speed limitation. On http://hijacker.rpc1.org/toshiba_nolimit/ I got the file.

When I start “update.bat” the following message appears

// — Copyright © TOSHIBA Corp. 1995-2002. All rights reserved. — //

I’m sure I have connected my Toshiba drive. In Windows and in the WinDos mode I have no problems to use the drive.
Why is it shown as not connected? Do you have any suggestions?

I solved the problem:

I have no disk drive, so I had to boot with a bootable cd-rom. Then I was able to flash the firmware. First I tried in WinXP (SP2) and that was NOT possible (see the message above).

So maybe the message is a help for other users.

The readme says clearly TRUE DOS!
