this is practically identical to the batch file I am using now (minus the
unnecessary ramdisk). part of the problem is the boot sector required by
isolinux, used by BFI.exe. hard to replicate unless you have dd or something.
I wrote a program to extract it from binary files (or from anywhere in a binary
file).I did not publish this program on sf.net yet, but I think I will, and put
it on http://sf.net/projects/extract512 - I didn't think anyone used it, but I
checked my logs and it was downloaded 42 times (whoopee.).
I still have the freedos ripcord package before it dropped off the web. in
fact, I am using a newer ISOLINUX that has more features.
