Boot from Floppy and see USB thumbdrive

[Poverty]

Can anyone tell me if it's possible to boot DOS from a floppy and have autoexec.bat assign a drive letter to my USB thumb drive?

I'd need to know how to set up both the config.sys and autoexec.bat files.

So far I have the system finding the USB thumb drive using USBASPI.SYS, but what I think I'm looking for is a USB equivalent to the MSCDEX.EXE file to assign the drive letter.

Please Help.

Poverty struck.

Welcome to Windrivers poverty

a good deal of info here (http://www.bootdisk.com/usb.htm) should put you on the right track.

I already looked there, but all these examples are for a USB CD, and all use MSCDEX or some other file meant for a CDROM. MSCDEX is the file that assigns the drive letter to the CD. What I'm looking for is something that will assign a drive letter to the USB thumbdrive.

I believe the bios has to support booting from a usb device (http://www.memorykeytools.com/) But you want to boot from floppy and assign a drive letter that way.

you got as far as others did (http://forums.windrivers.com/showthread.php?t=50037)


darkhorse is back! (http://www.stefan2000.com/darkehorse/PC/DOS/Drivers/USB/) with a new section - have a look at the cypress mass storage driver.

I've tried DUSE. Here are the results:

Starting.......

devicehigh=a:\emm386.exe
device=a:\usbaspi.sys
dos=high,umb

--------------------------------
Autoexec.bat

@echo off
duseldr a:\duse.exe drives=1


Does anyone know what I need to do to "install" the USB Flash Disk on Drive D: as a device?

Has anyone else been able to load and read a USB thumbdrive from DOS?

Please help,

With help from another chat conference, I finally did it.

My config.sys looks like:

device=a:\himem.sys
devicehigh=a:\emm386.exe
Device=a:\usbaspi.sys
devicehigh=di1000dd.sys
dos=high,umb

Nothing of any consequence in the Autoexec.bat.

And DOS sees my 512MB thumb drive and assigns it a drive letter.
