Phoenix v6 Bios usb drive size limitation?

Specs: Windows XP, Pantum 4 / 512Meg
I can't boot into hp Pavilion 772c when I have certain usb devices hooked up. It seems that if I hook up an external usb drive larger then 2 Terra's that's when I can't boot from the Sata C: drive in the computer it's self. So from my understanding upgrading the Bios should salve this problem. But I must do my homework first and that why I am asking all you for your expertise.

My Bios is a: Phoenix - award Bios v6.0 Rev. 3.04 5/10/02

So if anyone knows what is the maxim usb drive size that my bios can except to allow normal boot for the Bios I already have. and if anyone know what version of the Phoenix Bios saports dives of up to 4 Terra's. That help me determine if my plan of actio.

WinXP supports up to 2TB drives formatted NTFS. So, your problem is the OS, not the BIOS.

I am not shore that this is the cause in this case. I could be wrong but I have a dell computer witch also has XP that has no problems booting up with the same drives I have tried with this hp computer. Yet I know the dell computer doesn't like the supper large because video and audio files don't recorded and play well from them.

I suspected it's the bios because windows xp doesn't seem to get started at all, the win xp logo with a green progress bar Never Comes Up, after the bios the screen flashes 3 times (like it dose in a regular boot) and is plain blank, nothing it's just sits there. So if you think it is really is windows xp and since anther computer I have that also has xp does boot with these drives. Then are you suggesting that I update windows?

Well since MS is no longer supporting xp dos anyone know how to get the latest service pack and other updates for manual update? at least that's worth a try.

Beyond that I will would like to know the limitation of the Bois, good thing to know.

The bios must be trying to identify everything connected and is having a problem with large USB drives. Try removing any USB boot devices from the boot order. Maybe if it's not in the boot lineup the bios will ignore it.

Most bios update descriptions will tell you what issues were addressed in the update. If something like external drives were updated then a bios update might be a good idea. Otherwise, I guess you could try one anyway but that's one of those things you have to be careful with.

What sp version is installed on your computer now? SP3 was the last one for XP. If that's what you have now then you're maxxed out. Most of the other updates were security related and wouldn't affect an external drive.

Thanks for the feedback. I had already tried every setting in the bios I could find including reducing the boot order down to just the hard drive it's self.

I will look into the other things you brought up and get back to you tomorrow. Thanks again.

At least one drive manufacturer had a work around for drives larger than 2TB. See the link below.

Thanks OtheHill,

From what you have provided to me, I gather that the reason that the bios can't continue with the boot proses might be do to it encountering a file system that is not in a MBR format. That it gets stuck when it sees something like a GPT.

So in theory, a quick way to prove this would be to go to the Disk Management, go to the partition of the usb 3TB (or 4TB) drive and delete it. If the computer reboots with that drive attached with no partition then it's MBR issue and sub partitioning the drives would become one option to fix it. The only inconvenience with the Disk Management is that it doesn't display the MBR or GPT of the drives, but it may not be necessary to display that to me if it's doing it right.

Also thanks for introducing me to this software. Since this project is about setting up a bunch of backup drives to the hp computer that will be accessible to all the other computers to backup to by means of the network. Essentially making the hp a backup server. Even though I had already decided on my main backup software, with the idea that most of my back up drives would be sort of mirrors of there counterparts for quick swop out when a main drive fails, There are still a few details (like properly mirroring a boot up drive over a network) that I had not quite ironed out. The software you munched has some pretty neat features worth considering in my approach. So thank you for that. But I still need to get past this issue first.

"My Bios is a: Phoenix - award Bios v6.0 Rev. 3.04 5/10/02"

That is a very old system. Since you stated it's an HP, the HP site is the only place to be looking for a BIOS update. You might be able to cross flash to an MSI BIOS (MSI made the board) if you can find the MSI board that your board is based on, but I wouldn't recommend it unless you'll willing to risk bricking the board.
