Gate A20 Option (Fast)
This option defines how the system handles legacy software that was written
for an earlier generation of processors.
Typematic Rate Setting (Disabled)
If this option is enabled, you can use the following two options to set the
typematic rate and the typematic delay settings for your keyboard.
- Typematic Rate (Chars/Sec):
This option defines how many characters per second are generated by
a held-down key.
- Typematic Delay (Msec):
This option defines how many milliseconds must elapse before a
held-down key begins generating repeat characters.
Security Option (Setup)
If you have installed password protection, this option defines if the password
is required at system start up or if it is only required when a user tries to enter
the Setup Utility.
APIC Mode (Enabled)
APIC is the acronym for advanced programmable interrupt controller. The
APIC was developed originally for multiprocessor systems to overcome the
limitations of the standard 15 interrupts available along with the conflicts
arising from two processors simultaneously trying to generate interrupt
requests. For any modern operating systems, APIC should be enabled, only
in legacy operating systems could there be a need to disable APIC and run in
legacy PIC mode
MPS Version Control For OS (1.4)
This setting specifies the APIC lookup table used for best compatibility with
the OS. In Microsoft operating systems, Windows NT 3.51 and older should
be configured to Version 1.1, any more recent operating system should be
set to 1.4.
OS Select For DRAM > 64 MB (Non-OS2)
This setting only applies if you are running OS2 and are using more than 4
MB of system memory. All current DDR modules as those required in your
motherboards are of greater density than 64 MB. Therefore, in the rare case
you are running OS2, this setting has to be changed to the OS2 tab in order to
support the higher memory space
HDD S.M.A.R.T Capability (Disabled)
The S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) system
is a diagnostics technology that monitors and predicts device performance
S.M.A.R.T. software resides on both the disk drive and the host computer. The
disk drive software monitors the internal performance of the motors, media,
heads and electronics of the drive. The host software monitors the overall
reliability status of the drive. If a device failure is predicted, the host software
warns the user of the impending condition and advises appropriate actions to
protect the data.
