Using USB Flash Drives under DOS - USB 2.0
After fumbling around, I actually managed to load a USB 2.0 flash drive under DOS using a floppy disk!!!
device=duse.exe 4.4
device=USBASPI.SYS /r /v /norst Seems to be version 2.x
device=Di1000dd.SYS From years ago
Just don't know why?
My motherboard only supports USB 1.1. My original flash drive was also a 32M USB 1.1 one.
The method to drive this flash drive under DOS with a floppy disk:
device=USBASPI.SYS /// Version 1.x
device=Di1000dd.SYS /// From years ago
It worked and I used it for almost two years, then gave it to my brother because it was too small.
I got a new 128M USB 2.0 one, and using this floppy disk to drive it didn't work. I then replaced USBASPI.SYS with the 2.x version, still no good. I downloaded the [Super Universal MS-DOS 7.10 Boot Disk] which is said to have many features, made it into a floppy disk, selected tests 3 and 4 when booting. Selecting 3 failed to load, selecting 4 caused a crash. Loading too many programs led to compatibility issues, so I looked for other methods elsewhere. But what I found in China was all jumbled up, so I muddled through experiments. After many failures, I finally found the method to recognize my flash drive on a USB 1.1 motherboard:
device=duse.exe
device=USBASPI.SYS
device=Di1000dd.SYS
I think my achievement has reached the leading level in China!!!
Everyone test it out
Of course, I think the method to recognize my flash drive on a USB 2.0 motherboard is
device=duse.exe
device=ASPIEHCI.SYS
device=Di1000dd.SYS
But I haven't tested it yet
