Explanation of Certification 
In order to ensure the highest level of compatibility and support, NeXT has developed a process to comprehensively test specific PC-Compatible system configurations with NEXTSTEP for Intel 
Processors.

·	Each specific system configuration has been subjected to a suite of compatibility tests by the NeXT Quality Assurance group.

·	A detailed NeXTAnswer support document is available listing the specific configuration tested, and any setup information required to configure the system for NEXTSTEP.

·	Because of the detailed information available to customers and NeXT's Support personnel, NeXT delivers the best technical support on certified configurations.

·	A system platform is loosely referred to as "Certified" if it has one or more certified configurations, but all the benefits of certification are available only to users of the specific certified configurations.

·	Only the manufacturing revisions of a system unit and its add-on cards listed in the NeXTAnswer are certified.

·	NeXT certification does not necessarily mean "error free."  Certified systems may contain detected or undetected compatibility problems.

Certified Configurations:
NeXT has certified the following configuration:

Digital DECpc XL 560
	32MB RAM
	406MB SCSI hard disk
	Diamond Viper PCI with 2MB VRAM
	Intel EtherExpress 16
	MediaVision Pro AudioSpectrum 16
	Digital VRC16 color monitor
	
Setup and Installation:
NeXT used an Adaptec 1542CF SCSI adapter to certify this system.  Because of a bug in NEXTSTEP, occasional kernel panics may occur under 3.2 while booting with this adapter.  While repeated attempts should result in a successful boot, NeXT recommends obtaining a copy of the latest Adaptec driver (available through NeXTAnswers), which fixes this bug.

Because both Adaptec SCSI adapters and Pro AudioSpectrum 16 cards use IRQ level 11 by default, a conflict will occur in Configure.app.  NeXT recommends changing the IRQ level of the Pro AudioSpectrum card to 15.

Since the display driver for the Diamond Viper video card does not ship with NEXTSTEP 3.2, it is necessary to use the "Default VGA Adapter" driver during the installation process, then install the "Weitek P9000-based Display Adapter" driver (available through NeXTAnswers) manually.

Known Problems:
·	When switching from Full-Screen to In-a-Window mode with SoftPC, the SoftPC window may appear corrupted.  This problem will go away with the first screen update.  To force it to make its first screen update, press the Return key two or three times to cause the corrupted screen to scroll up.

·	In certain video modes, the mouse cursor may leave behind tiny colored dots.  These will disappear with the first screen update.

·	The 44KHz stereo tests are known to cause system panics under NEXTSTEP 3.2 when an Adaptec 154x SCSI card and a Pro AudioSpectrum Sound card are present.

·	The Release 3.2 serial port driver may become unreliable at speeds above19,200 baud. A bug in this driver may cause your computer to crash when serial port activity goes above an undetermined threshhold.

·	Make sure that all unused or disabled PCI slots have their IRQ set to "None" as shown in the BIOS settings listed above.  In particular, if any of these slots has IRQ 11 assigned to it, the Adaptec SCSI controller (which uses IRQ 11 by default) will fail with "AHA Timeout" errors.
