I have a Dell and update the BIOS BEFORE I installed SP2. That was the recommendation at Dell's website. The update itself took less than 10 seconds. I downloaded the non-floppy version and installed it according to the instruction at the Dell download site.
I recently had to reformate my computer, Dell, Win XP Pro, 2.0 GHz, 1GB, cable modem. Before I did this, because of SP2, I looked at the Dell site and it said to update to the latest Bios before I installed SP2, everything was going fine, reformated no problems, did windows updates up to SP2, then I when to install/update, from disc's I had previously made, the Bios, after an hour I quit the process because even though it said it was doing its thing, nothing seemed to be happening. How long does it take to update the Bios? The computer is working fine, even without this update, just want to know. Thanks in advance for your input. Eddie
