Software • BIOS System for System Units with Socket 7 (ZIF)
External Cache
Makes it possible to prevent the use of the integrated L2 cache on the mainboard.
Switching off the internal cache slows down the system considerably, and is
therefore not advisable.
Quick Power On Self Test
When set to Enabled, POST speeds up (no detailed memory test).
Boot Sequence
Determines the order for booting the devices. A range of different combinations
are available.
At the beginning of the sequence, an operating system is sought on the first
device. If there is none found, the BIOS searches for the next device etc. If an
operating system is found on a device, then this drive is booted. However if the
BIOS does not find an operating system, an error message appears on the
screen.
If there is no hard disk on the drive which was finally booted, then it is
automatically assigned drive designation A. If an additional disk drive is available,
then it is automatically assigned the drive designation B.
Swap Floppy Drive
This field is effective only in systems with two diskette drives (IPC5600, see the
section "Operating 3.5" Diskette Drives").
Selecting Enabled assigns the drive designation B to drive A and the drive
designation A to drive B .
Boot Up Floppy Seek
When Enabled, BIOS tests (searches for) floppy drives during the POST to
determine whether they have 40 or 80 tracks.
Note: Only 360 KByte diskettes have 40 tracks. All diskettes with 720 KByte, 1.2
MByte and 1.44 MByte have 80 tracks. Since very few modern PCs have 40-track
floppy drives, we recommend that you disable this field to save time.
