Device, and Third Boot Device. Options for
this category are the same as for the First Boot
Device.
System Cache Enables or disables the secondary cache
memory.
System Speed Specifies the processor speed at which your
system boots and runs. Options for this cate-
gory are Fast (for the microprocessor’s rated
speed) and Compatible, which helps accommo-
date speed-sensitive application programs by
disabling all cache memory.

mode is activated at boot.
Floppy Access Determines whether your system can write
data to a diskette inserted in a diskette drive.
Options are Read/Write and Read Only.
Setup Prompt Enables (the default) or disables the prompt to
enter the system setup program during the boot
routine.
Hard Disk Pre-Delay Enables or disables (the default) a delay before
the BIOS accesses a hard-disk drive to avoid
accessing the drive before it has been initial-
ized. Only older hard-disk drives may need this
delay.
Typematic Rate
Programming
