What is the memory hole at 15M-16M?
Question:
What is the memory hole at 15M-16M?
Answer:
In the CMOS setup often under the
Advanced Chipset Features there is an option for Memory Hole at
15M-16M, with the available options of Disabled and
Enabled. This setting allows users to enable or disable the 1MB
of memory required by some ISA
expansion cards.
Enabling this feature will decrease your memory by 1MB and allow
the few ISA cards that require this memory to properly work on your
computer. However, with some motherboards enabling this feature
could also disable all memory above 15MB and cause other significant
issues. Because ISA cards are rarely used today and because many
motherboards don't even have an ISA slot on them we recommend all
users keep this option at the default setting of Disabled.
