  1. Hi,

    I have a laptop with only CD. I downloaded updated BIOS file but the file requested a diskette in order to update BIOS.

    what can i do to update BIOS without diskette?

    If your computer can boot from an USB device and that you have some USB flash, format a bootable DOS partition on it and put the required files on it.

    What else, you can burn a bootable DOS CD. You will just not be able to backup the older BIOS if you don't have a FAT32 HDD partition.

    Hi DragonMaster,

    how can i do a bootable DOS CD?

    HP gave me a downloaded BIOS upfile. The file will automatically prompt me a screen to indicate which diskette drive i should put. (selection only 'A' or 'B').
    Once it got the bootable DOS CD, how can i tranfer the necessary BIOS data to the bootable DOS CD?

    You need to use a virtual floppy drive:

    Install the driver and enable the drive. Let the HP utility write its stuff and unmount your floppy. Ask your CD burning software to create a bootable CD and point it to the floppy image you got from the virtual drive.

    An other option,

    If you have Nero, you can make the floppy in an other computer, start Nero, select bootable CD and select that you want to get the boot image from the floppy drive.

    I have Nero Express and that's the only option I've got.

    Some motherboards have utillities that can flash the BIOS on Windows.

    Also but it doesn't seem to be his case.

    That's why I will spend 13$ more in my new PC. It still can be useful, even if I can boot with my ZIP or USB Flash.

    Well I'm sure that just the shipping will cost more than getting it locally.
