Non riesco ad aggiornare il bios del Promise SATA150 TX2plus!

[demo]

Ragazzi ho scaricato l'ultimo bios relativo a questo controller che ho su nForce 2 ma non riesco ad avere successo con l'update.
Vi riporto la procedura della Promise Technology:

[INSTALLATION]


1.1 Make a BIOS Upgrade Disk

a. Insert a blank floppy disk into the floppy drive.

b. Using an unzip utility, extract the files from the
BIOS ZIP file to the floppy disk

c. Label the diskette "SATA150 BIOS Utility Disk" and remove
the disk from the floppy drive.

1.2 Boot your system

a. Insert a DOS Boot Disk in the floppy drive.

b. Turn on your system.

c. When your system boots to the command line, remove the Boot Disk from
the floppy drive.

1.3 Upgrade the SATA150 BIOS

a. Insert the SATA150 BIOS Utility Disk into the floppy drive.

b. At the A:\> prompt, type DIR and press Enter to see the name of the
BIOS upgrade (.bin) file.

c. At the A:\> prompt, type the following:

pflashb8 /f XXXbXXXX.bin

Where XXXbXXXX.bin is the name of the upgrade BIOS file, identified in
step b, above.

d. Press Enter. The utility will report the following:

Updating card 0 ....OK.

e. Remove the SATA150 BIOS Utility Disk and reboot your system.

This completes the BIOS upgrade procedure.

Faccio così ma quel maledetto "OK" non arriva mai
Disabilito la protezione Flash da MoBo ma niente
Potete aiutarmi per piacere?
