DOS USB Drivers
There are several ways folks are getting their USB CDroms, Hard Drives, and other drives to work in DOS. One is using what's known as DUSE driver system. The second method is using what looks somewhat like standard CDrom driver files and a USB driver. Both methods appear to require loading an usbaspiX.sys file first in config.sys in most cases. The third method is a bootdisk from a USB vendor. Method 4 is getting good reviews also.
METHOD 1 - The DUSE System
Example 1 Using DUSE
[config.sys]
device=a:\himem.sys
devicehigh=a:\emm386.exe
device=a:\usbaspi.sys
dos=high,umb
Note: You can find a usbspi.sys on the internet or use on of the five different versions I've found in the Download Files section at the bottom of the page
[autoexec.bat]
@echo off
duseldr a:\duse.exe
MSCDEX /D:USBCDROM /S /M:15 /V
Example 2 Using DUSE
[config.sys]
device=a:\himem.sys
DEVICE=a:\duse.exe
[autoexec.bat]
MSCDEX /D:USBCDROM /S /M:15 /V
METHOD 2 - The usbaspi.sys/usbcd.sys System - Example 1
As noted, this method seems just like loading IDE drivers, with the added entry of the usbaspiX file. The following are the relevant portions taken from a modified config.sys and autoexec.bat file which was designed to work with a Windows 98 OEM Bootdisk with the ramdrive.
The complete config.sys and autoexec.bat replacement files are available for download below, and you might want to start first with just copying them to your OEM bootdisk along with the relevant drivers and then experiment later with getting them to work on your Customized disk.
[config.sys - example 1]
device=himem.sys /testmem
ff
device=usbaspiX.sys
device=usbcdX.sys /D:mscd001
[config.sys example 2 - USB Floppy in only port, "sometimes" allows switching to CDrom after boot]
device=himem.sys /testmem
ff
device=ramfd.sys
device=usbaspiX.sys /W
device=usbcdX.sys /D:mscd001
[autoexec.bat]
LH %ramd%:\MSCDEX.EXE /D:mscd001 /L:%CDROM%
METHOD 2 - The usbaspi.sys/usbcd.sys System - Example 2
"I finally got my Belkin external drive enclosure with a WD 120gb drive to work in DOS, and then perform a GHOST image", wrote don b. "Here's the files and config.sys that worked."
[config.sys]
device=himem.sys /testmem
ff
devicehigh=usbaspi1.sys
devicehigh=di1000dd.sys
devicehigh=usbcd2.sys /d:USBCD001
LASTDRIVE = Z
[autoexec.bat]
don b. noted that either the standard Ghost or Win98X autoexec.bat worked as is.
METHOD 2 - The usbaspi.sys/usbcd.sys System - Example 3
Herbert H. writes: "I Just solved my problem by using the files from the "virtual" DOS drive ghost03 makes when you run interactive mode. It uses IOmega USB drivers and Guest.exe. It alowed me to use my Western Digital external USB HD in DOS.
[config.sys]
LASTDRIVE=Z
DEVICE = usbaspi4.sys /int /all
DEVICE = usbaspi5.sys /int /all
DEVICE = usbaspi5.sys /int /all /D1
DEVICE = usbcdX.sys /D:cd2
DEVICE = OAKCDROM.SYS /D:cd1 [For his IDE CDrom]
METHOD 3 - The datoptic System
A USB 4 DOS bootdisk has been posted here called dat.exe
The key driver files in dat.exe include:
usbaspi.sys 37,090 bytes
nj32disk.sys 15,808
sbp2aspi.sys 28,836
datoptic.com recommends the following config.sys for it's USB/1394 products. It's been reported tho that their drivers also work for other brands as well.
[menu]
menuitem=USB,USB Boot
menuitem=1394,1394 Boot
menudefault=USB,30
menucolor=7,0
[USB]
DEVICE = USBASPI.SYS
[1394]
DEVICE = SBP2ASPI.SYS
[COMMON]
DEVICE = NJ32DISK.SYS /R
LASTDRIVE=Z
METHOD 4 - The Iomega Way
Ben B. wrote:
I built a boot disk to access a USB external hard drive from DOS using drivers included with Norton Ghost. 2003. Since Ghost can write to the external drive in DOS, I figured I could copy its drivers. Turns out they are from Iomega. I wanted to access the external drive to run a disk wiping program. Autoexec.bat and Config.sys can be much improved, but this is the bare bones of the boot disk. Note that the Iomega drivers will work with any USB external hard disk and are not proprietary to Iomega drives (mine is a Western Digital).
Config.sys:
DEVICE=aspiehci.sys /int /all
LASTDRIVE=Z
Autoexec.bat:
@echo off
GUEST.EXE
Contents of my boot disk:
aspiehci.sys [Iomega USB 2.0 driver]
Autoexec.bat
Command.com
Config.sys
guest.exe [Another Iomega program required to access the USB drive]
Io.sys
Msdos.sys
Thanks Ben. Your letter has enough information tho to put folks on the right track to find the drivers themselves. If folks want to save some time tho they can get the drivers here.

The USBdrivers collection includes 5 different usbaspi.sys and 2 usbcd.sys files, the iomega drivers, the ramfd.sys driver, and the modified Win98 OEM config.sys and autoexec.bat files. You will have to experiment to see which one works for you.
The key driver files I've put together for you in the [USBdriver] collection include:
ramfd.sys 22,012 bytes
usbaspi1.sys 39,093
usbaspi2.sys 43,528
usbaspi3.sys 37,090
usbaspi4.sys 49,242
usbaspi5.sys 50,606
usbcd1.sys 5,509
usbcd2.sys 35,456
di1000dd.sys 16,368
Iomega:
aspiehci.sys 52,106
aspiehcj.sys 49,772 [renamed - older version of aspiehci.sys]
aspiohci.sys 42,242
aspinhci.sys 50,606
guest.exe 8.5 32,396
Please keep in mind that DOS USB CDrom/HDD/zip/etc. drivers is a brand new and developing area so there is no one single method that is guaranteed to work on every PC. If you try a few methods and have no luck, keep at it and dont worry as I'm confident there is enough information here to get at least 99% of the USB drives to work in dos.
