How to Update video Bios

Howdy folks,
Just a quick question as to what command do I use to
update my Video Bios from F1 to F4 in the readme.txt of the flash utility is
says as follows:
Using FLASH utility follow below:

ATIFLASH -p 0 Filename

For example, file name is AR64S.F2 in drive A:. The command is:

ATIFLASH -p 0 A:AR64S.F2

The FLASH utility supports the following VGA card of GIGABYTE:

AV32S
AV64S
AV32ST-NF
AG32S-HP
AG32S
AR64D-TF
AR64S-H
AP64D
AP64DH
AP64DL
AV32DG
AR64DG
AP128DGH
AP128DH3
AF128DGH-GH
AF64DG-H
R9000 PLUS
R9000
R9100-B3
R9100-C3

Now my Video card is the Gigabyte Radeon 9200 with 64MB DDR ram

Chip Vendor : ATI
Chip Type: Radeon 9200 (RV280)
Model Name: R9200-64D

So can anyone offer some advice and I do need to update the BIOS to resolve
a issue not updating just because there is a update.

Thanks,
Shane
