So if you want to change this Serial Number you need to change the CPU as it is encoded into the CPU and can be used to trace the individual computer that it was fitted to originally. Your BIOS serial is saved via software, not hardware. Like anything else that's software based, the BIOS serial can be changed. The serial number data, as well as date and time are kept running even when the computer is powered off through a tiny battery called the CMOS battery.

Ok, i have a HP Tablet PC TC1100, also known as a Tx1100. I have a need to change the serial number and the asset tag.

I've tried using DMI tools however they can not write to this Bios. The bios version is as fellows: Bios Vendor = Phoenix Bios Version = FirstBIOS Pro 2002 Q3 Bios Released = After reading a HP customer solution ( ), I come to beleive that DMITool4.0 would be capable of writing to the bios and i suspect would be able to change the values that i wish to change. However this is only availabe internaly in HP and not to the public. So that was the end of that. So, what are your thoughts?

Does any one know how to write to a bios that seems to be un-writable. In the worst case i could remove the bios and solder a new one on. I have no checked but i'm pretty sure its not socketed.

Any help would be great. Ok, after much marking around, and a whole night of slow progress. To edit any section of a phenoix bios, a simple way of doing it is to download Phoenix WinPhlash, this is used to write to the bios. You just need a copy of the rom for your bios, so that you can edit it how you want and then flash it to the bios using WinPhlash. For me, i obtained a perfect copy from my computer manuafacture, by downloading a bios flash update. Which when used updates the bios, but not the DMI strings as i needed. But if you extract the executeble's, theres a copy of the rom, which includes the DMI strings.

So use this rom, with Phoenix's WinPhlash. And you can edit your bios however you want. It did the job for me. PS> I need job, so any company finds this work intresting, hire me.

Hi, I don't believe 'Phoenix WinPhlash' is the same as 'Phoenix BIOS editor' but it may do the job. I'm not exactly sure where I got it from I'm sure you could still find it around on the net. When you extract them from the update. You can edit them with text editors to be what you want them to be. And then from there you can use them with Phoenix WinPhlash.

I did this successfully with 2 laptops. I'd love to hear how you go. And also just wondering but what bois version is it that your working with. And what type of computer is it in.
