Halt on
During the power-on self-test (POST), the computer stops if the BIOS detects a hardware
error. You can tell the BIOS to ignore certain errors during POST and continue the boot-up
process. These are the selections:
No errors
POST does not stop for any errors.
All errors
If the BIOS detects any non-fatal error, POST stops and prompts
you to take corrective action.
All, But
Keyboard
POST does not stop for a keyboard error, but stops for all other
errors.
All, But Diskette
POST does not stop for diskette drive errors, but stops for all
other errors.

other errors.

Memory
You cannot change any values in the Memory fields; they are only for your information. The
fields show the total installed random access memory (RAM) and amounts allocated to base
memory, extended memory, and other (high) memory. RAM is counted in kilobytes (KB:
approximately one thousand bytes) and megabytes (MB: approximately one million bytes).
RAM is the computer's working memory, where the computer stores programs and data
currently being used, so they are accessible to the CPU. Modern personal computers may
contain up to 64 MB, 128 MB, or more.
Base Memory
Typically 640 KB. Also called conventional memory. The DOS operating system and
conventional applications use this area.
Extended Memory
Above the 1-MB boundary. Early IBM personal computers could not use memory above 1
MB, but current PCs and their software can use extended memory.
