Test for unexpected interrupts. First do an

 

 

STI for hot interrupts. Secondly, test the NMI

 

 

for an unexpected interrupt. Thirdly, enable

 

 

the parity checkers and read from memory,

 

 

checking for an unexpected interrupt.

Determine and test the amount of extended

 

 

memory available. Determine if memory

 

 

exists by writing to a few strategic locations

 

 

and see if the data can be read back. If so,

 

 

perform an address-line test and a RAM test

 

 

on the memory. Save the total extended

 

 

memory size in the CMOS at cmosExtended.

 

 

 

 

62h

 

Perform an address line test on A0 to the

 

 

amount of memory available. This test is

 

 

dependent on the processor, since the test

 

 

will vary depending on the width of mem-

 

 

ory (16 or 32 bits). This test will also use A20

 

 

as the skew address to prevent corruption

 

 

of the system memory.

Set cache registers to their CMOS values if

 

 

CMOS is valid, unless auto configuration is
