Hey! I know those! I have 'em too!
If you have the QLogic SanSurfer, it's a breeze. You can do it runtime, remote, and it's pretty quick. You still need to reboot the machine afterwards, but you can schedule that for after hours. Otherwise, you'd have to see if there is a Windows update package, I don't know that offhand. There is always booting from a floppy ..
BTW, you can use the sansurfer also to update the driver remotely; you're downlevel there and there is some reason to use the STORport driver instead of the SCSIport, but read the docs and find out what it was again because I don't remember why. Current STORport driver version is 9.1.2.19.
There is no newer BIOS than 3.47, firmware is at least at 3.03.19 (that's where I am) but I think there's a newer version than that.
