|
|
|
|
|
| |||
Processor Test | Tests the processor’s registers. Test failure causes the boot process to | |||||||
abort. |
|

|
|
|
|
|
| |||
System (BIOS) ROM Test | Calculates an | |||||||
abort. |
|
| ||||||
|
|
| ||||||
|
|
|
|
|
| |||
RAM Refresh Timer Test | Tests the RAM refresh timer circuitry. Test failure causes the boot process | |||||||
to abort. |
|
| ||||||
|
|
| ||||||
|
|
|
|
|
| |||
| Checks the first 64 KB of system RAM used to store data corresponding to | |||||||
Interrupt RAM Test | various system interrupt vector addresses. Test failures cause the boot | |||||||
| process to abort. |
|
| |||||
|
|
|
|
|
| |||
| Tests the system ROM BIOS and shadows it. Failure to shadow the ROM | |||||||
Shadow the System ROM | BIOS will cause an error code to display. The boot process will continue, | |||||||
BIOS | but the system will execute from ROM. This test is not performed after a | |||||||
| soft reset (using |
|
|
|
| and | ). | |

| |||
Load CMOS Memory | Checks the serial EEPROM and returns an error code if it has been | |||||||
corrupted. Copies the contents of the EEPROM into CMOS RAM. | ||||||||
| ||||||||
|
|
|
|
|
| |||
CMOS RAM Test | Checks the CMOS RAM for | |||||||
checksum(s). Test failure causes error codes to display. | ||||||||
| ||||||||
|
|
|
|
|
| |||
Internal Cache | Tests the processor’s internal | |||||||
Memory Test | error code to display and the boot process to abort. | |||||||
|
|
|
|
|
|
|
| |
| Video Tests |
|
|
| Initializes the video subsystem, tests the video shadow RAM, and, if |
Initialize the Video | required, shadows the video BIOS. A failure causes an error code to |
| display, but the boot process continues. |
