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:

Keyboard

If the keyboard is not really necessary in the system, you can disable it. In this way the system can bootstrap without error.

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:

ƒSystem memory pattern test

ƒKeyboard detection

ƒFloppy disk presence (seek test)

ƒRTC time test
