1B-1E Reserved
1F Set EISA Mode If EISA non-volatile memory checksum is good,
execute EISA initialization. If not, execute ISA
tests and clear EISA mode flag.
Test EISA Configuration Memory Integrity
(checksum & communication interface).
20 Enable Slot 0 Initialize slot 0 (System Board).
21-2F Enable Slots 1-15 Initialize slots 1 through 15.
30 Size Base and Extended
Memory Size base memory from 256KB to 640KB and
extended memory above 1 MB.
31 Test Base and Extended
Memory Test base memory from 256KB to 640KB and
extended memory above 1 MB using various
patterns.
NOTE: This will be skipped in ISA mode and can
be « skipped » with ESC key in EISA mode.
32 Test EISA Extended
Memory If EISA Mode flag is set then test EISA memory
found in slots initialization.
NOTE: This will be skipped in ISA mode and can
be « skipped » with ESC key in EISA mode.
