2.2 Installing OS-9 V2.4.5 on an Empty Harddisk

It is recommended to install the operating system on a fresh formatted

harddisk. Boot the system from floppy, load the appropriate harddisk

descriptor and format the harddisk (see Section2.1 ‘Booting from Floppy

Disk’).

1. Load the back utility from your boot disk and change the current

directory to harddisk.

$ load back

$ chd /h0

2. Copy the all floppy disks in ascending order to the harddisk using the

back utility.

$ back /d0 /h0 -r

Use the '-r' (rewrite) option because disks contain some files twice.

In some cases the OS-9 was delivered with an addendum disk with new or

bugfixed modules. See the file ReadMe.Addendum on this disk for further

details.

3. Generate a new boot file on the harddisk with os9gen. Examine the

sample bootlist file in CMDS/BOOTOBJS. Add the drivers and

descriptors needed for the system. For the information which drivers

and descriptors are needed, refer to Chapter3 ‘Drivers and

Descriptors’.

$ chd /h0/cmds/bootobjs

$ dmode /h0 format=on

$ os9gen /h0 -z=bootlist -eb=200

The harddisk descriptor may have the Format Inhibit bit set. This results

in error 000:255 (E$Format) when trying to write to sector0 (like

os9gen). Use the dmode utility to clear this bit (dmode /h0 format=on).

4. Reset the system and reboot the operating system.

The memory size is set to 2MB per default, so you have to configure the

memory list in the init module (see Section2.6 ‘Memory Configuration

with MemList’).
