Motherboard Firmware and Drivers

Welcome to Digital's distribution site for Alpha Motherboard Firmware and Drivers. Here you can find AlphaBIOS and ARC Firmware, HAL and Installation Floppies for Windows NT, design files for fabricating your own Alpha motherboards, as well as links to drivers and miscellaneous resources for Alpha systems on other Digital sites.

Our newest Alpha Motherboards (PC164LX, PC164SX) run AlphaBIOS Firmware. Previous Alpha Motherboards (PC164, EB164, PC64, EB64+, EB66+, EB66) run ARC Firmware. AlphaBIOS provides an improved user interface, more user features, and takes advantage of new capabilities on newer Motherboards.

Windows NT 4.0 Files for AlphaBIOS Motherboards:

Digital recommends that you upgrade AlphaBIOS whenever you upgrade the HAL on your system. The versions of AlphaBIOS and HAL listed in the table below are intended to work together.

HAL400_D.zip
HAL.DLL for Windows NT 4.0 on PC164 based systems
Fixes problem with "invalid scatter/gather pte" for "audio scrubbing" in non-linear video editors.
This is an update to the HAL.DLL distributed on Microsoft's Windows NT 4.0 CD-ROM. It is the same HAL.DLL that is contained in the 400D4494.zip and 400D4497.zip files and so is redundant if you have installed Windows NT 4.0 using one of those files as your installation floppy.

Version: n/a
