hi, I've search a lot, and the flashing routine is not so easy to understand. But we are on the right direction. regards
Block-Protection bits ooh... finally this thread is getting me a little excited with the prospect of a solution to our HP Phoenix woes!
@ YEN I suggest to remove "PHOENIX" from the title of this thread as we are only trying to solve "HP COMPAQ" bios's flashing issues with HPQFlash/Rompaq regards
Another important question for me is the following: What does the notebook when it's restarted after the BIOS flash? HP notebooks restart several times when a new BIOS has been installed. Does HPQFlash only write to a temporary region? If so, then I think the configuration which ares should be written is found in the Image itself. That would be a problem for us though.
hi, I think I've found THE solution, i cant test it tonight (gmt+1) because I've completely explode my laptop 6910p searching an hypothetic hardware solution and now that will take a couple of hours to make it working again. So as soon as possible i will explain the way to unlock the protected zone of the BIOS. see you soon.
hi, My machine works now but I'm a bit disappointed because the command HPBI103 write VPRO ON crash. anyway a HPBI103 read VPRO returns the following message: Assets Utility Version 1.02 Copyright (c) 2006 Hewlett-Packard Corporation VPro Disabled Descriptor locked Management Engine disabled Flash Protection Override disabled May be the write routine have been removed from the tool or something else, i'am sure a lot of people will investigate soon. @gregg, mutante, if you have some time to spend on this subject, can you have a look with IDA. regards
Really interesting tool... I'm looking asm code but this tool is really not easy to understand. Maybe mutante can help us. We just need to find a way to enable Flash Protection Override, right? PS: On my laptop, VPro is enabled . But I really don't know theses tools and what is Vpro... PS2: Are you sure this tool is made for our laptops? Maybe some other HP DMI Tools are available...
hi, thats the only tool from HP DMI collection who works on my 6910p, it's often use to make visible SLIC tables with the command HPBI103 write slp on. This hidden VPRO command will certainly help us to enable Flash Protection Override. If the write command have been removed we can anyway analyze the read command and see witch part of the DMI table is concerned. I'm pretty sure the solution is here, hidden but here. can you please give the model of your laptop and send a copy of what is return by the command on your machine, (type hpbi103 vpro> result.txt) thanks for the help
HP 8710w Code: Assets Utility Version 1.02 Copyright (c) 2006 Hewlett-Packard Corporation VPro Enabled Descriptor locked Management Engine enabled Flash Protection Override disabled
hi, I agree, but the Flash Protection Override disabled/enable information flag is in the DMI table and we have to find the way to change it. With IDA i aim to find the read routine of this flag and then make a small com file to change it. May be I'm wrong.
