Halt On
During the power-on self-test (POST), the computer stops if the BIOS detects a
hardware error. You can program the BIOS to ignore certain errors during POST and
continue the boot-up process. The possible selections are listed in the following table.
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.
Other Memory
Between 640 KB and 1 MB; often called High Memory. DOS may load terminate-and-
stay-resident (TSR) programs, such as device drivers, in this area, to free as much
conventional memory as possible for applications. Lines in your CONFIG.SYS file that start
with LOADHIGH load programs into high memory.
Table 4-5: POST Specific Commands
Command POST Action
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.
All, But Disk/Key POST does not stop for a keyboard or disk
error, but stops for all other errors.
