Appendix B Test Descriptions Timer Test This test checks the accuracy of the timer count by calibrating it against the periodic interrupt of the real time clock (RTC). Real Time Clock Test This test checks the accuracy of the real time clock by calibrating it against the system timer. It also does a pattern test on RTC. CMOS Validity Test This test checks the condition of AT CMOS RAM (non-volatile memory). The test assures that the CMOS battery is in good condition and that the CMOS RAM checksum is correct. Speaker This tests checks the functionality of your Speaker by playing a short song. PCI System Test This test scans the PCI bus and finds out all the PCI devices. Then it uses alternative procedures to find out the same device. It checks for all valid combinations of PCI bus number, device number and function number. It also checks validity of PCI BIOS32 service directories, and the generation of PCI special cycles. Multiprocessor Test This test works on Multiprocessor systems only. This test detects all the processors in the system and then checks if all the processors are able to communicate among themselves. It also checks ability to access the system memory and devices concurrently. Plug and Play Test This test works on Plug and Play systems only. This test detects all Plug and Play devices and checks if they are configured properly. It then does a pattern test on each Plug and Play device's configuration space. MMX Test This test runs only on CPUs with MMX made by Intel and AMD. MMX specific registers, instructions and arithmetic operations are tested. Matrix transpose test is carried out to assess MMX performance. DMI Test This test will verify that the DMI functions will return the DMI information correctly. 72

Timer Test
This test checks the accuracy of the timer count by calibrating it against the
periodic interrupt of the real time clock (RTC).
Real Time Clock Test
This test checks the accuracy of the real time clock by calibrating it against the
system timer. It also does a pattern test on RTC.
CMOS Validity Test
This test checks the condition of AT CMOS RAM (non-volatile memory). The
test assures that the CMOS battery is in good condition and that the CMOS RAM
checksum is correct.
Speaker
This tests checks the functionality of your Speaker by playing a short song.
PCI System Test
This test scans the PCI bus and finds out all the PCI devices. Then it uses
alternative procedures to find out the same device. It checks for all valid
combinations of PCI bus number, device number and function number. It also
checks validity of PCI BIOS32 service directories, and the generation of PCI
special cycles.
Multiprocessor Test
This test works on Multiprocessor systems only. This test detects all the
processors in the system and then checks if all the processors are able to
communicate among themselves. It also checks ability to access the system
memory and devices concurrently.
Plug and Play Test
This test works on Plug and Play systems only. This test detects all Plug and Play
devices and checks if they are configured properly. It then does a pattern test on
each Plug and Play device's configuration space.
MMX Test
This test runs only on CPUs with MMX made by Intel and AMD. MMX specific
registers, instructions and arithmetic operations are tested. Matrix transpose test
is carried out to assess MMX performance.
DMI Test
This test will verify that the DMI functions will return the DMI information
correctly.
