My BIOS is v6, there is a v8

So, I have to flash

Upgrading the BIOS doesn't hurt, but this by itself won't solve the problem unless your OS supports 48-bit addressing
The 200GB HDD is a slave to a 20GB HDD on which I have the NOS.

According to what I read, it WILL sort it when flashed............
it takes SP3, I'm at SP4 + everything since..........

I can't believe how worried I am about doing this .............
Do it without a thought at work, on OTHER PEOPLES PC'S ...............


Ah well.
Lets DO IT......

Backups ready .................................. Check
It's midnight, and I'm wearing sunglasses


Back soon.........................................ish
