    Ok, here is your homework.

    - Flash your BIOS to the original A13 if it's not already updated.
    - Boot up existing Windows and install RW-Everything
    - Save the ACPI Table report (eg: C840_A13_AcpiTbls.rw)
    - Get the latest of AndyP's PhoenixTool
    - Extract it to C:\Temp
    - Copy the original BIOS executable C840A131.EXE and the RW-Everything report to C:\Temp
    - Run the PhoenixTool and create your own SLIC'ed BIOS updater
    - Rename the SLIC'ed BIOS updater to a DOS-friendly filename like "C840SLIC.EXE"
    - Boot to DOS and flash the BIOS

    Good luck getting drivers.
    - NVIDIA driver search for 72.30_win2kxp.zip
    - 3Com NIC driver if you find it, let me know

    UPDATE: See below for 3Com NIC and PCTel Modem driver.

    Thankyou tqhoang

    you are correct concerning drivers for 3COM had no luck with finding drivers for device. so i guess it's a wash to operating win 7 on this laptop. i don't have confidence to perform task above I've only been on this site which is awesome for 2 days. My idea with hopes with bios mod will allow device drivers to load such as 3com so on. reading now it solve product key issuse. thx for your time once again this laptop is older but it work well for me i've upgrade to pc2700 along with 2.6 cpu finally with large hard drive which i've done myself. homework you gave above i would love to do however i think i will be over my head. bad student

    I was able to get the 3Com 3c920 Ethernet and Intel AC97 audio drivers via the "Update Driver" button on the device. The chicken & egg situation was solved by installing an Intel 2915ABG mini-pci wireless card using the Vista 32-bit driver.

    Here's the 3Com Ethernet driver (rather old but it works) and the Intel AC97 audio driver.

    Also for the PCTel modem, you can use Dell's Windows XP driver...I just installed it manually instead of running the setup program.

    Make sure you're flashing the BIOS from a real DOS boot disk. You can make a DOS boot floppy using the "driver-free" one from bootdisk.com. After you make the floppy, copy the SLIC BIOS to the floppy, then reboot and flash.

    What do you mean you have bought a floppy drive ? if so that may not be practical some bioses are larger that size of floppy disk, that is why i mentioned use bootable usb thumbdrive or cd.

    Do not give the file any arguments. Only type either "C840SLIC" or "C840SLIC.EXE" (without the quotes). I think you might have been typing the "period" as another character and it thinks you were trying to pass it arguments on the command-line.

    BTW, no payment is allowed here...it's all pro bono.
