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.
