    I was running WINPLASH to do a BIOS update but seconds before the flash was complete the laptop just shut off.

    I want to follow the instructions for PHOENIX bios recovery located here: h**p://forums.mydigitallife.net/threads/870-Bios-Recovery-Procedures

    The only issue I don't understand is that I have 3 BIOS files, not just one to rename to "bios.wph"

    I have these files: 089CF45W.UMA 0898F45W.M9X 0898F45W.M10

    Within the instructions of the .rar file containing the modded bios and tools to perform the mod, the instructions were different then they were on the post of containing the modded bios. In the post the author said to rename each of the three files I mentioned above to BIOS.WPH before running WINPLASH. I wasn't sure what to do here so I started with the first file mentioned thinking the flashing process would ask me to provide the second file. Then I ran WINFLASH, and it started to perform the flash and was almost finished when my laptop just turned off. It was plugged in with full battery life.

    My first question is this: What procedure do I use to recover the system?
    My second question is this: if WINPLASH only needs one file, BIOS.WPH, to perform the flash, how do I perform it?


    I have modded 4 BIOS to SLIC 2.1 with complete success activating windows 7. This one has thrown me for a loop.

    I apologize for the ** in the http links. The forum won't let me post links until I have over 20 posts.

    I tried using the HP Disk storage format tool and followed the instructions posted here for BIOS recovery.

    I tried using both the modded bios and the original bios, each containing three bios files.

    I put all three files on the boot disk I used and also took a copy of the first file (089CF45W.UMA) and renamed it to bios.wph

    Still no success. It does appear the the laptop is accessing the USB drive during the process, but its a 4 gig and I think that might be too big. No floppy drive available.

    1. The 3 BIOS files are likely for 3 variants of your system. The extensions (UMA, M9X, M10) make me think that the difference is the graphics adapter (UMA=Intel, M9X/M10=ATI graphics?). Which graphics does your system have?

    2. If it's accessing your memory stick, then your 4GB stick might be ok. The key is to have the right PHLASH16.EXE. The latest version I have is PHLASH16 v1.7.0.21.

    I havent been able to bring the system back....have tried all three bios files.

    Anyone here ever had to revive a bricked HP Pavilion laptop that uses a similar bios update procedure?

    I had a quick look at the HP website, the HP zv5000 does have the M9x/M10 ATI GPU's. zv5000 refers to a specific model, and the range which include around 40 different variations. The first question is, apart from the graphics module, does each model in the series use the same BIOS?

    I'm not sure how much benefit Windows 7 will give you on a 7 year old laptop, or whether you'll be able to get all the required drivers.

    For the USB stick, its probably been formatted as FAT32. For BIOS recovery you may need to format it as FAT16 (typically known as just FAT) instead of FAT32.

    You may not be able to select FAT16 from Windows format or the HP format tool. You can go to the command prompt, and type in:
    Format [drive letter]: /fs:fat
    You can also add /q to the end of that which will skip the verification of data area, but since its a bios flash its probably safer to leave it on.

    On a size note, but since I said format the USB drive:
    When you format the drive back to FAT32, remember that flash type drives (USB sticks, SD cards etc) require 32KB clusters, at 4kb clusters performance will be impaired. Its very common for people to format USB and SD cards incorrectly then be stuck with noticeably lower performance that what they should have.

    You can use the SD card format tool safely on USB sticks, and is probably the best option to ensure the 4gb operates at the correct speed after you have finished with it requiring FAT.

    The SD card format tool is available here:
    http://www.sdcard.org/consumers/formatter_3/

    Only SD cards and USB drives will show under that format tool.

    NEVER format a USB or SD card with the Windows format without manually selecting '32 kilobytes' as the 'Allocation Unit Size'. It will still work if you don't, but it will severely impact performance. If anyone has had slower than expected performance (even 50 percent or more) on a USB stick its probably because they've formatted it, and done so using the default FAT32 4k allocation unit size.

    At this point burfadel I have determined that the ROMpaq download containing the program to flash the BIOS for my laptop, the zx5000, is used on about 30 other HP laptops, including the zv5000. I know now where I went wrong and bricked the board during the flash procedure in windows (I renamed the files with _SLIC at the end incorrectly and proceeded with the flash.)

    Yeah the HP tool won't let me do FAT16 but I found a few tools that do. Thanks for giving me the DOS commands to do so.

    The next issue I believe I am having is getting the correct BOOT files put on the USB stick. I have tried multiple kinds to no avail (Minidos, the one windows 98 uses when creating a bootable disk.)

    Assuming I have formatted the drive correctly with FAT16 and have the correct files to make the stick bootable my final issue is which of the four methods listed on the "Bios Recovery Procedures" sticky will work. I had tried them all before realizing I was formatting with FAT32.

    There are also two other procedures I am trying, CRISDISK and PEN DRIVE RECOVERY.

    I believe that the ROMpaq has three different potential files to be renamed to BIOS.WPH or BIOS.ROM, depending on the proceedure.

    After reading the Hardware Repair Manual pdf from HPs website for the laptop I was able to confirm that the .UMA is for the systems with either an Intel or Nvidia graphics chip. the M9X file is for systems with the ATI 9200 chip and the M10 is the systems with the ATI 9600 video chip.

    Im too tired to take the laptop apart but I am almost completely certain it has the ATI 9200 video chipset. So I will be renaming the .M9X file to BIOS.WPH or BIOS.ROM and going through each of the methods again, this time formatting with FAT16.

    Im gonna be pissed if its not working simply because the stick is 4GB or the system doesn't even support booting from a stick for BIOS recovery.

    ???Would a USB floppy disk drive work in place of an internal one, which I do not have???

    I will report my results so that if I am successful they will be left here on the forum in case someone goes and does something dumb as renaming the files to be flashed to bios incorrectly and bricking their ancient HP Pavilion zx5000 that most likely isn't going to run so well on Windows 7 anyway.

    Well I have came to the conclusion that I am not going to be able to revive this BIOS without a USB Floppy drive and floppy disk.

    BUMMER.
