The following procedures have been tested to work successfully with various Notebook and Desktop computers by our engineers. Because of the growing complexity of new computer hardware and software, there is always possibility that the USB DOS driver and the installation procedures that we provide cannot enable you to install the Windows OS onto your system. In this case, you may need to check with your hardware manufacturers to determine the problem. Addonics cannot provide any technical support beyond our own products as our technical staffs have no knowledge of the computer hardware and software that you have. Often time, there might be existing hardware problems or damaged installation CDs that prevent the proper installation of the Windows OS. Please note that the current USB DOS driver can only support USB 1.1 speed.
As always, you should make a back up copy of all your important data before reinstalling the Windows OS. Addonics is not liable for data loss, time loss or claim of system damage resulted from the instructions outlined below.
* Make sure you have enough space in your local hard drive. At least 4 GB or higher. The USB cable is an Addonics USB 2.0 interface cable. The process involved
Installing Windows 2000, XP using the Addonics USB CD-ROM, DVD-ROM, DVD/CDRW or DVD-R/RW drive. (For Windows 98SE or Me, please proceed to the next section)
The procedures are practically identical to Windows 2000 or XP as described above. Except instead of copying the I386 folder to the hard drive, you will copy the Windows 98SE folder or the Windows Me folder to the hard drive.
If your system does not have a built-in floppy drive, you may use a USB floppy, ZIP drive, CD or USB hard drive. But your system BIOS must have support for booting from USB floppy, ZIP, CD-ROM or hard drive. Make sure the media that you use to boot the system contains all the files from the dosboot.img in step 5.
Alternative USB DOS drivers and procedure from USB hard drives or USB optical drives:
Due to different versions of Windows 98, USB optical drives, and motherboard hardware, there is no universal solution to have all USB devices supported under DOS. If the drivers using the Cypress DUSE USB drivers above are not working for you, you may wish to try the following procedure.
1. Load Windows 98 bootdisk (I recommend the Windows 98 OEM version over the Windows 98SE or DOS 6.22 bootdisk) onto a floppy disk. Verify that the disk is able to boot to A: command prompt correctly by inserting it into the floppy drive on the target computer and selecting the floppy drive as the first boot priority.
2. Download f2h_usb.exe from the following location:
3. Extract f2h_usb.exe to any directory on your computer. Locate the following files from the root directory, and copy them over to the bootdisk.
USBASPI (v2.15) allows USB connected mass storage devices to be mapped as ASPI devices.
4. Download "Motto Hairu" driver (Assigns drive letter to an ASPI mass storage device) from the following location:
5. Extract the filename below from mhairudos.zip onto the bootdisk. Do not extract the USBASPI.SYS and RAMFD.SYS located in mhairudos.zip onto the floppy.
6. Right click on AUTOEXEC.BAT and select "Edit" to edit the file in Notepad. Remove all the information contained within, and replace with the text below. Save the file with the same extension (.BAT). mscdex.sys can be configured to assign a drive letter starting from a certain letter using /l: as a parameter. In this example "M" is the first drive letter to be assigned.
mscdex.exe /d:mscd001 /d:USBCD001 /l:M /M:16 /v
7. Right click on CONFIG.SYS and select "Edit" to edit the file in Notepad. Remove all the information contained within, and replace with the text below. Save the file with the same extension (.SYS).
device=USBASPI.SYS /v /w
8. Now you are ready to boot from the bootdisk. When the bootdisk loads, it will assign drive letters for each USB mass storage device starting from the drive letter you specified earlier in AUTOEXEC.BAT or CONFIG.SYS. If your USB optical drive is detected, you can continue from Step 11 above.
