Bios update to boot from usb cd-rom

Question

Hi everyone, I'm trying to boot from an external usb cd-rom on my Latitude C840 but I haven't find a way yet; I was guessing if updating my bios will be a solution. Has anyone already done it ? In case wich bios version have I to download?

Hi, No ' C ' series will boot from USB. As you have a CD and floppy built in, either will work.                                                                                        Regards Chris

Hi,   You should be able to download a DOS bootable floppy, or the .exe file, make a DOS bootable CD, then after DOS loads, run the .exe file. You may need to change the boot order, or use an F12 at the splash screen to for a 1 time boot.

You need to get a startup disk image. That will be required to copy the io.sys and msdos.sys and command.com from. Any of the Bootable images will work.

Then Download the M-Systems Dell USB Memory Key. boot utilityand format your usb thumb drive with the make my flash drive bootable option then point to c:\

Then when you boot hit F12 and it should show the USB flash device as a bootable device IF the bios in your system supports that.
