Flashing BIOS/Making bootable DOS filsystem on USB stick
I have a problem with my laptop, and before Dell will consider taking it back, I have to go through their checklist and make sure I've tried everything on that list first. This includes upgrading the BIOS. The problem is that Dell provides the BIOS upgrade in two forms: (a) A DOS executable (b) A Windows self-contained utility to make a boot floppy Since I have neither Windows nor a floppy disk, I'll have to be creative. I thought that maybe I could install some boot code on a USB flash drive, newfs_msdos, and copy FreeDOS along with the executable (a) mentioned above. Problem is: How do I install the boot code on the drive? FreeDOS provides a floppy-image, so I thought I could just dd that to my USB drive, and boot off of that. But I need to put the BIOS upgrade utility on the disk as well, and it is 784 kiB. Could I grow the image? Any pointer appreciated Svein Halvor signature.asc Description: OpenPGP digital signature

Re: Flashing BIOS/Making bootable DOS filsystem on USB stick
You have a few options: go to bootdisk.org and download a suitable verision. There are many floppy images there. For instance the win98 diskette version, when booted creates a ramdrive you can switch to, then change the usb disk. Or boot with two usb drives inserted, the bootable one and the one with the BIOS flash utility. Or use a winpe bootable CD. You can find one and information at: http://www.nu2.nu/pebuilder/ You can customize the image you build including your Windows BIOS utility. Or buy or borrow a USB floppy drive. -Derek At 02:38 PM 5/25/2006, Svein Halvor Halvorsen wrote: I have a problem with my laptop, and before Dell will consider taking it back, I have to go through their checklist and make sure I've tried everything on that list first.

Re: Flashing BIOS/Making bootable DOS filsystem on USB stick
Svein, I had a situation with needing to boot into dos to flash firmware. I booted using a Freedos CD with my utilities on the same CD. I think I had to create a RAM drive to use the firmware upgrade utility. -Jason Ellison On Thu, 25 May 2006, Svein Halvor Halvorsen wrote: Adrian Pavone wrote: What about using 2 floppies?

For instance the win98 diskette version, when booted creates a ramdrive you can switch to, then change the usb disk. Or boot with two usb drives inserted, the bootable one and the one with the BIOS flash utility. Will DOS be able to load USB devices? I thought this only worked when I booted off the device using some BIOS magic. Or use a winpe bootable CD. You can find one and information at: http://www.nu2.nu/pebuilder/ You can customize the image you build including your Windows BIOS utility. This requires Windows, I think. Or buy or borrow a USB floppy drive. Bah! I'd rather not buy new hardware just for this one predicament. This is what I have readily available: - Computer running FreeBSD - USB CDRW-drive - 512 MiB USB flash drive - A 1.44 MiB FreeDOS floppy image with 111 kiB free space - A FreeDOS iso9660 image - A 784 kiB DOS executable for flashing my BIOS Using these I need to make some sort of bootable DOS device (either CD or USB flash drive) that contains the above mentioned BIOS upgrade utility. Could I either: - Get the BIOS utility onto the ISO file without braking the boot code - Use the floppy image to make a bootable USB disk somehow?
