BOOT SECTOR STATUS

The boot sector must be valid in order to be reconized by the HD
BOOT ROM. The boot sector becomes automatically valid as soon as
the settings are saved by pressing key 'S'.

OPTION 1 : BOOT DEVICE

When a valid boot sector has been detected. DOS will be booted
from the chosen device. If floppy is selected, DOS will be
booted from floppy if a disk is inserted. Otherwise 'Missing
disk' is reported. Note that settings 2 to 7 are ignored when
the boot device is set to floppy. If the hard disk is selected.
DOS will be booted from the boot record.

OPTION 2 : BOOT RECORD

This is the record from which the DOS is booted. Record one is
recommended but any other record can be used too. The most
important thing is that the boot record is empty when B-DOS is
copied to it because the DOS must be at the start of a record in
order to be booted (as with a floppy disk). In the remarks
section of the option menu you can see if the selected boot
record contains a bootable DOS. If the record you want to use as
boot record is not empty then you can copy that record to a
other record, erase all files in the boot record,copy B-DOS to
it and copy the files back from the other record to the boot
record. (if there's at least 10K free).

HARD DISK BOOTING

DOS is booted from the hard disk if the following conditions are
met:

HD BOOT ROM FITTED
VALID BOOTSECTOR
BOOT DEVICE IS HARD DISK
BOOT RECORD CONTAINS BOOTABLE DOS.
SPACE BAR IS NOT PRESSED.

If one of these conditions isn't met. The HD BOOT ROM aborts the
hard disk boot sequence and attempts to boot from floppy.

DVAR SETTINGS

Each time this program is loaded. The existing boot sector is
scanned and loads the last saved settings from it if the boot
sector was valid. Otherwise default settings are used.
The settings are copied to the DVARS (DOS variables) only after
B-DOS has been booted from hard disk.

OPTION 2: ACTIVITY BORDER

With this option you can choose the type of border changes.

- 0 No border changes.
- 1 black, blue border.
- 2 black, red border.
- 3 black,blue,red, magneta border.
- 4 black, green border.
- 5 black, blue, green, cyan border.
- 6 black, red, green, yellow border.
- 7 black,blue,red,magneta,green,cyan,yellow,white
    border.

OPTION 3: DEFAULT DRIVE

Drive selected after DOS is booted. Loads the AUTO* file from
this device.

OPTION 4: DEFAULT RECORD

Record selected after DOS is booted. Loads AUTO* file from this
record if default device is set to hard disk.

OPTION 6: SPACE CHARACTER

The spaces in filenames are printed with this character instead
of a space. Enter a character of your choice or press return to
use a space chr.

OPTION 7: DATES ON DIR.

Valid date and time of a file are displayed in a directory in
MODE 3 if this option is set to print.

SAVING NEW SETTINGS

Once you've chosen the settings. Press 'S' to save them together
with valid boot code required for the HD BOOT ROM to the boot
sector. Saving can be done at any time. Even if the hard disk
boot conditions are not all met. This allowes you to select a
boot record now and copy the DOS to it later.

Once all hard disk boot conditions are met. Try pressing RESET
or BOOT 1. DOS will be booted from hard disk.
