Sony VAIO Motherboard Dead...

I've been trying to find a solution to this on the net for a while.

Basically, a BIOS update went bad, etc... and I'm trying to use Phoenix Bios Crisis on my VAIO FE690P. I've tried all of the normal hotkeys, Fn + B, Win + Esc, etc. with a USB Floppy Drive and there is no activity. My guess is that Sony, in their usual fashion, decided to make it non-standard and proprietary. They also don't like to publish service manuals, either...

Anyone know if Sonys have a hotkey at all or possibly a jumper somewhere on the motherboard?

Am plagued with a similar problem. Did you find the key combination to access the Boot Block of your Sony?

The usual Fn + B Win + B etc do not work.

Grateful if you can help bring my Vaio FE31Z back from being a brick to life :)

it seems you need to use an LPT key
