Post subject: WPH Bios with HP NXseries |
 |
|
Hello there.
I've came across this forum while searching for information on bios modification for my NX7300 (GM945Express). I was abot to try my new moded bios when I have noticed that the well known Phoenix Crisis Disk recovery method doesn't work on my laptop. Win+B trick turns the recovery mode on but... there are no WPH bioses for NXseries (and some other new HP Notebooks). There was even a thread on official HP forums about a faulty bios for nx7300 (F.0D) which has killed a lot of laptops wihout ANY reaction from HP and without any chance for bios recovery with Phoenix Crisis Disk). The only thing HP would offer to some of those poor users was a motherboar replacement. Now the official thread is gone (at least I can't access it) and its only available thorugh google cache http://209.85.135.104/search?q=cache:KdAWUUQfc30J:forums11.itrc.hp.com/service/forums/bizsupport/questionanswer.do%3FthreadId%3D1254348+nx7300+F.0D&hl=pl&ct=clnk&cd=7&client=opera
So before doing some stupid things I have decided to create a WPH bios by myself.
The F.0D Bios is gone from HP page - so I have downloaded it and after extracting i tried to open ROM.BIN with PBE - OK I knew that was comming. So I have tried to backup my bios with winphlash (which requires a WPH bios to dump the current one). I have used a WPH bios file from DV2000t which is the closest model to nx7300 i could find (please let me know If you know about a different model which is more similar to nx7300) Whinphlas has dumped the bios. Upon opening with PBE a new error has appeared | Code: | | Invalid ROM length! |
- well that is a progress isn't it?
I have also tried a WPH file from DV6000t - | Code: | | Invalid ROM length! |
I have compared the sizes of dv2000t and dv6000t WPH files with dumped bioses created with the use of them and
dv2000t WPH - 1 083 102 bytes -- dumped bios from nx7300 - 1 083 075 bytes
dv6000t WPH - 1 102 246 bytes -- dumped bios from nx7300 - 1 102 246 bytes
So what's with the Invalid ROM length? Does anyone have an idea If I can fix this error? When I have compared the dumped nx7300 bios with the one from dv2000 or dv6000 with winhex I have seen that the structure of the files is completly different)Is dumping wph bios fron nx series possible at all?
