I need to create a DOS boot ISO image that I can add some files to. This is going to be used to update BIOS. The vendor provided the update, but the instructions say to copy them to a DOS-bootable floppy disk (yeah, right).
I've spent the better part of the day looking for a bootable CD image, and I can't find one on line. Of course that could just be because I'm looking in the wrong places. I did manage to find a couple of things that looked promising, but they ended up not working for a variety of reasons. For instance I was able to extract the files and boot image from one of the disks at allbootdisks, but all it has is floppy support, and even though the files I added were present on the CD (I could see them in windows) they weren't visible when I booted the CD.
I did find a good DOS install for a USB drive at http://www.jamesonline.ca/support/dos-on-usb-support that creates a sort of virtual disk that it looks like I could copy my BIOS updater stuff onto. Would it work to use those files on the CD file system and the BootImage.ima file from the allbootdisks ISO?
I find it hard to believe that I'm the only one to run into this situation. I've made slipstreamed XP disks before, so I'm sort of familiar with the general principles, but I'm obviously missing something here and would appreciate any help.
