    hello to all
    i have read some of the posts here about bios recover i think i have undestud the main of the procedure, but i have some questions:
    i have download the bios from hp site:sp34600.exe
    i have extracted the files to a new folder and i have 3 bios files (i think):
    - 309DF21.P20
    - 309EF21.P20
    - 309DF21.P21
    well i was confused i expect only one bios file!!! . . . after loking and read some of those files i found something in the flash1.ini (yes i must say also that the bios file only work in windows mode):
    #PCI\Ven_8086&DEV_2592=309DH01.wph
    #PCI\Ven_1002&DEV_5653=309EH01.wph
    ROM_PCI_A!KA=80001000,25928086,0,309DF21.P20
    ROM_PCI_A!KA=80001000,25928086,1,309DF21.P21
    ROM_PCI_A!KA=80010000,56531002,0,309EF21.P20
    i have look in the internet about those controlers and i think my bios is the 309EF21.P20, because the PCI\Ven_8086&DEV_2592 is the intel video driver and the PCI\Ven_1002&DEV_5653 is the ati video driver, and my hp comes whit one ati radeon x700.
    of corse im not 100% sure about this.
    i have tryed some of those procedures to recover the bios but until now nothing . . .
    i must say that the hp had some problems, it was "stopped" for a wile, and when i decide to work with it again it has some problems that i have assumed that it needs one bios update.
    as i refered hp bios only work in windows mode but like the hp was erratic when i update it went wrong . . . but at the time it was the only metod that i knew to flash the bios.
    meen wile i found this forum i have read some posts and i wolld like to ask to someone that can help me
    the mais questions are the bios file is the correct one? can i try to update the bios with those metods once my bios only is flashable from windows?
    thanks in advance,
    sorry for my english

    its ati per hp specs for DV4235EA
    try 309EF21.P20
    rename to 309E.wph as the filename or 309E.bin or 309EF21.wph or .bin or .rom

    or 309E.WPH or BIN

    E= ATI
    D= Intel video
