OS-9 V2.4 on EUROCOM-17 2 Installing OS-9 V2.4.5

Software Manual 7

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

sample bootlist file in CMDS/BOOTOBJS and add the necessary

drivers and descriptors. 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).

5. 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’).

6. Now copy everything from the renamed directories that is not already

contained in the new directory. Typically things which do not belong

to the OS-9 operating system. Check carefully if this software is still

operateable before usage.

2.4 68040 Cache Configuration

2.4.1 Standard OS-9

Configuration

including SSM

The usage of the ssm040 module also implies the usage of the original

Microware syscache040 module, which is located in the file

syscache040.

In this case the cache operating mode is selected by the ssm040 code:

ssm040.cbsup - cache enabled in supervisor state, copy back mode

ssm040 - cache enabled in supervisor state, write through mode

If you want to change cache modes and areas in user state, the cache list in

module init.a has to be changed (see Section2.4.3 ‘Cache Configuration

with CacheList’ for details).
