Good afternoon, all:
I have a computer which, when I boot DOS, does not see the USB
stick plugged into the computer. Thanks to Patrick, PA5AEI, I
now have the USB stick running under DOS. I'm actually using
FreeDOS for this experiment.
The key is two device drivers: USBASPI.SYS and ASPIDISK.SYS.
Along with the proper config.sys file, these detect my USB stick
and DOS makes it C: or D:! Note: I had to let DOS start
booting, put a pause (using the MENU directive) in config.sys,
and plug the USB stick after DOS starts.
The critical parts of the config.sys file are:
device=usbaspi.sys /v /slow
device=aspidisk.sys
This works on two of my computers with USB slots and which
did not work with DOS without these drivers.
I got the two ".sys" files from a Puppy Linux startup disk image.
http://www.goosee.com/puppy/boot2pup
and used the VFD (Virtual Floppy Driver) to open the image. These
files are readily available from the web. You can see

I didn't know this was even possible!
Thanks, Patrick.
73,
Mark, KD4D
