PCI USB 2.0 Enabler for DOS

USB 2.0 Mass Storage Enabler is a class enabler. In other words it will enable any PCI USB Adapter regardless of PCI adapter manufacturer and model.

Fully compatible with Norton Ghost and PowerQuest Drive Image under MS-DOS and Windows 9x DOS.

• Supports any USB 2.0 and USB 1.1 PCI adapter.
• Provides build-in support for USB 2.0 and USB 1.1 hard disks and CD-ROMs/DVD-ROMs
• Cooperates with USB BIOS. Do not disturb functionality of USB devices (such as USB keyboard and mouse) configured by BIOS.
• Relocates parts of enabler code to upper memory automatically.
• Supports any number of attached hard disk and CD/DVD-ROM devices (except DOS Point Enabler for ATA Cards).
• Built-in resource manager with true PnP support of hardware configuration.
• Supports both: original DOS (e.g. MS-DOS 6.22) as well as DOS included with Windows 95/98.
• Can be loaded via CONFIG.SYS, AUTOEXEC.BAT or simply started from DOS command prompt.
• Support driver unload (unless third party drivers were loaded).
• No DOS memory (inside of the 1st Megabyte) required for hardware configuration.
• Provides full LBA support for disks of any size. Large disks are supported.
• Provides full INT 13h support, including extension. Most utilities (e.g. FORMAT.COM, FDISK.EXE, Norton Utilities, etc.) are supported.
• User may freely assign drive letters to partitions, except if Enabler is loaded from CONFIG.SYS.
• Does not provide hot-swap support. The Mass storage device should be connected to the computer before Enabler is started.
• Provides set of flexible configuration options via command line or via external .INI file.
• Extensive diagnostic output on user request.
• Supports multiple adapters of the same type.
• Support backup and restore to/from NTFS partitions under Ghost 8.x.

Quick start:

Simply start driver from the command line or from autoexec.bat without parameters. The only restriction is that driver should be started after any memory manager such as HIMEM.SYS and EMM386.EXE.

Generally speaking as long as your USB devices are limited to USB disk and/or USB CD-ROM, you do not need any of third party USB driver - USBMASS will do the job.

In difference with any other USB software (such as Cypress Semiconductor Corporation DUSE 4.x), USBMASS by default do not change configuration of USB 2.0 or USB 1.1 PCI adapter assigned by BIOS and therefore do not disturb work of any device supported by BIOS.
