    You can save your current bios: You need Hwdirect and winhex (a bit complicated bit it works!)

    Install and open hwdirect, go to memory dump. Enter fff00000 without "h" and size 100000 without "h", press dump.
    Right click into window, select all, right click again, copy. Paste as new file into winhex. (Open winhex and press Shift + insert key) Make sure ASCII-hex is selected. Save file and upload, please!

    The original Phoenix bios file may contain extra data, which is usually no part of the bioscode itself.

    If you have a 1Mbyte bios just rename your dump to bios.rom and open / edit it with PBE!
    If it is AMI open and edit it with amimmwin, if Award remame it to bios.bin and open / edit it with cbrom and / or modbin.

    If it has got a smaller size cut and paste it into a new file before you edit it!

    1MByte starts at FFF00000
    512 kbyte at FFF80000
    256 kbyte at FFFC0000

    all till end of dump!

    @Yen thanks for your answer, i just have one more question...
    If I flash the bios without the extra data, ( that I can add if I have downloaded the original bios ) will it couse the board to brick ?
    That is if I have dumped the bios from the memmory and I cant get hold of the extra data.

    ok, I now seem to be having trouble booting from the CD. When my computer booted up I went into the Bios and checked to see the order of boot devices priority.

    1st boot device : [SM-MATs**tADVD-RAM]
    2nd boot device : [PM-SAMSUNG MP0804H]
    3rd boot device : [YUKON PXE]

    but Yukon comes up when ever i try to boot from the CD with the error
    PXE-E61 PXE-M0F. I then loaded optimal defaults and retried but no success. So I disabled [YUKON PXE] and then [PM-SAMSUNG MP0804H] in the bios boot devices priority.

    Then it says
    "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press any key" when the CD is in :confused:

    Can you boot from a windos install cd/dvd?
    If so then It looks like the cd isn't bootable.

    Some reported that it work with win98 dos boot disk, but you don't have a floppy.
    You can try other boot DOS CD. Yes it will be a sort of try and error, but it is a real AMI core8 bios for sure!
    You can also google about your error to find some information.

    Afudos allows also to backup the bios:
    Afudos /oami2.rom

    But therefore you have to use a writeable media.
    You can try this command to save it again also
    Afudos /oc:\ami2.rom

    to try to save it onto your c partition.

    Get a USB pen therefore and try to save your bios. After that can modify it again.
    We have to find a proper tool to flash.

    Is there a tool to update your bios on your CD which came with your laptop??
