Time
The time is displayed in standard format: hh mm ss (hours - minutes - seconds).
Date
The date is display in standard format: MMM DD YYYY (month - day - year).
Floppy disks
The floppy disks are numbered starting from one and the BIOS maps these drivers starting form the letter “A” .
Note: when the boot sequence starts from floppy disk number one (DOS letter “A”), any device selected as
floppy disk 1 can be a bootable disk. Obviously this device must represent a real bootable disk, with a proper
boot sector and containing a valid O.S.
All the
floppy disks can be configured with the same options. The CPU-1461 Module can perform floppy disk
options only if used together with an Add-on module where floppy disk ports are available:

1.44 MB Floppy disk 3 ½ - size 1.44 Mbytes Common used size
Integrated SSD
On-board Flash EEPROM Always available on all boards
Keyboard
If the keyboard is not really necessary in the system, you can disable it. In this way the system can bootstrap
without error.
Option Description Note
Not Present Keyboard presence ignored Useful for embedded systems
Present BIOS look for keyboard
Quick Boot
With quick boot enabled, the system takes less than 5 seconds for a bootstrapping. This improvement is
obtained to the disadvantage of BIOS tests (the setup must be correct and the peripheral must be connected
to the module and ready at the boot); in particular the following test are skipped:
ƒ
System memory pattern test
ƒ
Keyboard detection
ƒ
Floppy disk presence (seek test)
ƒ
RTC time test
Option Description Note
Disabled
Normal BIOS test are used
Enabled Reduce set of BIOS test are used
