The category determines whether the computer will stop if an error is detected during power up.
NO Errors The system boot will not stop for any error that may be detected and you
will be prompted.
All ErrorsWhenever the BIOS detects a non-fatal error the system boot will be stopped.
All, But Keyboard The system boot will not stop for all errors except a keyboard error.
(Default value)
All, But Diskette The system boot will not stop for all errors except a disk error.
All, But Disk/KeyThe system boot will not stop for all errors except keyboard and disk errors.
Memory
The category is display-only which is determined by POST (Power On Self Test) of the BIOS.
Base Memory
The POST of the BIOS will determine the amount of base (or conventional) memory installed
in the system.
The value of the base memory is typically 512 K for systems with 512K memory installed on
the motherboard, or 640 K for systems with 640 K or more memory installed on the motherboard.
Extended Memory
The BIOS determines how much extended memory is present during the POST.
This is the amount of memory located above 1MB in the CPUs memory address map.

During POST, BIOS will determine the floppy disk drive installed is 40 or 80 tracks. 360K type is
40 tracks 720K, 1.2M and 1.44M are all 80 tracks.
Enabled BIOS searches for floppy disk drive to determine it is 40 or 80 tracks. Note
that BIOS can not tell from 720K, 1.2M or 1.44M drive type as they are all
80tracks.
Disabled BIOS will not search for the type of floppy disk drive by track number. Note
that there will not be any warning message if the drive installed is 360K.
