Keyboard / Mouse Tests
Keyboard Test
Invokes a built-in keyboard self-test of the keyboard’s
microprocessor and tests for the presence of a keyboard and
for stuck keyboard keys. Test failure causes an error code to
display.
Mouse Test
If a mouse is present, invokes a built-in mouse self-test of the
mouse’s microprocessor and for stuck mouse buttons. 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.
Parallel 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 Tests
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
System Generation
Initiation of the system generation (SYSGEN) process, which
compares the configuration information stored in the CMOS
memory with the actual system. If a discrepancy is found, an
error code will be displayed.
Plug and PlayConfiguration
Configures any Plug and Play device detected (either PCI or
ISA):
•
All PCI devices, and any ISA device necessary for loading
the operating system will be configured for use.
•
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.
ERROR MESSAGES
When the PC is switched on or reset, a power-on hardware test is performed. If an error occurs,
an error message is displayed.
NOTE
HP’s new style BIOS does not display POST error
codes (such as 910B) which existed in the BIOS of
previous HP Vectra PCs.
