Read BIOS from ring3 exe

Hi,

How can I read BIOS memory from win32 exe file?
(without using VXD)
The code: mov EAX, [ESI] lead to page fault, of course :(

for win9x user GetCurrentProcess() and ReadProcessMemory()

Code:

        BIOS_START        equ 0F0000h

        BIOS_LENGTH        equ 010000h



        call        GetCurrentProcess



        push        0

        push        esp                        ; &lpNumberOfBytesRead

        push        BIOS_LENGTH

        push        offset lpBuffer                ; &buffer

        push        BIOS_START                ; bios start

        push        eax                        ; hCurrentProcess

        call        ReadProcessMemory

        pop        edx                        ; pop lpNumberOfBytesRead



(thnx to teston for this snippet)
