5 Power-On Self-Test and Error Messages

Order in Which the Tests are Performed

Protected Mode RAM Test

(Extended RAM)

Tests protected RAM in 64 KB segments above 1 MB. (This test is not done

during a reset using and Delete ). Test failure causes an error code to display.

 

Keyboard / Mouse Tests

 

 

 

Invokes a built-in keyboard self-test of the keyboard’s microprocessor and

Keyboard Test

tests for the presence of a keyboard and for stuck keyboard keys. Test

 

failure causes an error code to display.

 

 

 

If a mouse is present, invokes a built-in mouse self-test of the mouse’s

Mouse Test

microprocessor and for stuck mouse buttons. Test failure causes an error

 

code to display.

 

 

Network Test

If the network board is present, invokes a built-in self-test. Test failure

causes an error code to display.

 

 

 

 

Tests of Flexible Disk Drive A

Flexible Disk Controller

Subsystem Test

Tests for proper operation of the flexible disk controller. Test failure causes an error code to display.

Coprocessor Tests

Internal Numeric Coprocessor

Test

Checks for proper operation of the numeric coprocessor part of the processor. Test failure causes an error code to display.

Communication Port Tests

Parallel Port Test

Tests the integrated parallel port registers, as well as any other parallel

ports. Test failure causes an error code to display.

 

 

 

Serial Port Test

Tests the integrated serial port registers, as well as any other serial ports.

Test failure causes an error code to display.

 

 

 

 

Hard Disk Drive Tests

Hard Disk Controller Subsystem

Test

Tests for proper operation of the hard disk controller. Test failure causes an error code to display. The test does not detect hard disk replacement or changes in the size of the hard disk.

 

System Configuration Tests

 

 

 

Initiation of the system generation (SYSGEN) process, which compares the

System Generation

configuration information stored in the CMOS memory with the actual

 

system. If a discrepancy is found, an error code will be displayed.

 

 

 

Configures any Plug and Play device detected (either PCI or ISA):

Plug and Play

All PCI devices, and any ISA device necessary for loading the operating

system will be configured for use.

Configuration

Any ISA device that is not required for loading the operating system, will

 

be initialized (prepared for loading of a device driver), but not fully

 

configured for use.
