Is it any HP Probook 6550b BIOS to remove the WWAN Whitelist. I have an un2400 WWAN Card but my computer always gives me an 105 error with this card. Can any one help me? Thanks
I have Compaq 8710w Mobile Workstation. So I updated official BIOS version F.0F 25-nov-2008 by modded from this thread. After this I lost fingerprint sensor. There is no more such option in BIOS. I can't enable or disable it. And fingerprint sensor no more displayed in control panel. Any suggestions?
This is the original (not modified) results of BiosConfigUtility /GetConfig:bios.txt as your see, FingerPrint device enabled. But it not exist in control panel anymore. And now there is no such option in BIOS. Now I see next options under Builting devices in BIOS: That's all. No fingerprint. But anyway. I was tried to apply this (not modified settings) by biosconfigutility /setconfig:bios.txt. Rebooted and no changes. Problem still occure. I was tried flash official sp41953.exe. Rebooted. Problem still occure. After this I flashed sp41953_SLIC21_SLPon_no_whitelist.zip and still view same problem. :-( I flashed under Windows 7 SP1 x64 OS, if it important.
sorry I'm stuck, except if you've open the laptop and unplug the fingerprint sensor cable i don't see any reason for this issue.
This is true. When I first noticed the differences while debugging my code I thought this was a bug. I have spent some time studying them with a calculator and a piece of paper, and noticed that it was actually intended behavior. As it turned out there are two factors that influence the outcome of the packer. The first is that HP BIOS data sections do not seem to use maximum compression. I am unsure why this is the case, perhaps it is a mere tradeoff for better compression speed for the old days. Regardless, my compression code uses maximum possible window size, which means the algorithm searches all 4096 bytes for a best match (feel free to tweak this parameter, if need arises). For this reason the size of compressed data should be equal to or slightly smaller than the size of original compressed BIOS sections. The second factor is that this packer will search for a "history" match in reverse order as opposed to the HP packer. When it finds two or more possible candidates it selects the last one and ignores the rest... or was it the first one? I don't know, I forgot. Anyhow, the resulting compressed file will have a number of seemingly random binary differences when compared to the original BIOS section. While these differences should in theory result in identical data after decompression, I am unable to answer whether either will pose any problems for the actual BIOS unpacker. I assumed the code will handle it just fine, but that's the reason I published the code for testing. See ya! ~Relay
It does not brick it per se, as the new Probooks are designed to simply revert to good BIOS automatically (instant recovery) sebus
There seems to be some testing done with bios for nc4200/tc4200 but no report of success or failure. I'm willing to test no whitelist BIOS for HP NC4200
Nx9420, NW9440 Hi, Anybody can reupload the modded BIOS for these models? The upload link is not available THX
I can happily confirm that this BIOS works for NC4200. Typing from it right now with a SparkLAN WMIA-198N mini PCI card. @TTAV134 Many thanks. What kind of charity do you endorse? So I can chip in an contribution.
