BIOS update to support/ enable USB boot for H

Specs: Windows XP, 2.93 GHz / 1 G PC3200
I looking for a BIOS update to support/ enable USB boot for HP Pavilion a705w Desktop PC. I have seen allot of benefits for the new concept of "Take your desktop with you on USB" and would like to be able to set the bios for boot to USB. I looked in the bios and saw no such option in the current bios (2004) Therefore - I would like to find a flash update to update this bios. I also tried replacing the 40 gig HDD with a larger HDD and the unit told me that the restore disks that I made from the original system were not compatible with the system (because I was upgrading the HDD & this unit seems to have been built for replacement - rather than upgradable.)

Older bioses do not have the ability to boot from a USB connected drive.

If HP lists a Bios update in the software and driver downloads for your specific model on the HP web site, you could try flashing the bios with that, but it's doubtful it will add that ability if your bios doesn't already have the ability- that's something that would have probably been built into the original bios version .

Flashing the bios is the riskiest thing you can do to a computer.
If something goes wrong while flashing, you will end up with a computer that will not boot after you flash ! !
If I were you I wouldn't take the risk at all ! !

" I also tried replacing the 40 gig HDD with a larger HDD and the unit told me that the restore disks that I made from the original system were not compatible with the system (because I was upgrading the HDD & this unit seems to have been built for replacement - rather than upgradable.) "

HUH ?
The Restore disks, assuming they were made properly, will install the original software no matter what the size of the hard drive is !

The things that have to be right are:
- you can't use Restore disks with your computer that were intended to be used with another brand name model,
- the mboard model must be one of the ones the Restore disks were for,
- and the mboard must have a suitable brand name bios version.

To boot to a usb flash or hard drive use plop or slitaz or maybe smart boot manager.

To take your desktop with you, you may wish to look at portableapps.com
