    I acquired a new-ish laptop (an HP Pavilion dv6768se / dv6700 CTO / dv6700t) and Installed Windows 7 64. I then tried to flash the BIOS through Windows 7. I've done it plenty of times through XP and Vista. Even on Windows 8. Surely HP wouldn't leave a BIOS brickmaker on their website with absolutely no warning?

    Yes, they would.

    Windows 7 and WinPhlash happily let me erase the EEPROMs, but from what I can see, they did not to write any information back into them. It rebooted after completing the last aaaaaand - bricked. No post, nothing. Just lights and a high speed fan that slows after a bit.

    I've tried the WinCrisis recovery method, but all I get is a single beep. I removed all drives, optical and HD, network cables and battery and held Win-B. Tried both USB floppy disks and USB keys in various sizes, none seem to get any activity. I just get one (loud) short beep. The BIOS was F.27 and I was trying to flash F.34.
    The F.34 bios is SP52477 - The F.27 BIOS is sp38261. The motherboard is a Quanta (I don't recall the exact number, it started with a 30, like 30c0 or 30d0 or 30d3 - something like that), and I have tried file names of BIOS.WPH, 30CF.BIN, 30CF.WPH.

    hxxp://ftp.hp.com/pub/softpaq/sp38001-38500/sp38261.exe - F.27
    hxxp://ftp.hp.com/pub/softpaq/sp52001-52500/sp52477.exe - F.34

    (sorry, cannot post links yet)

    Interestingly, if I put no media in there whatsoever, I get a different startup sound, 1 long then 2 short beeps (also loud). And it loops.

    Any suggestions? Is a particular version of Phlash required? Does any files have to be in special place? Should there or shoudn't there be an autoexec.bat?

    All help will be greatly appreciated.

    Ok, I think I'm well and truly hosed. I suspect that BIOS write protect was turned on, and Windows 7 didn't check that. So the BIOS was happily erased, but not reprogrammed. It is completely my fault, I should've checked for that.

    I found that this model has a BIOS chip SOP-8 1 MB EEPROM (or so), a G266-25, somewhat near the wireless under some plastic.

    What kind of burner is recommended? I'm looking at a SOFI SP8-A USB high speed reader/burner with an additional SOP-8 clamp adapter to read/burn the chip. It'll take on the order of a month to get here. Before I order, does anyone have any suggestions or recommendations?
