Re: diskboot source code   
In the master source tree, it is utils/d/diskboot/ but I havent checked if that's been echoed to the public svn server.

Re: diskboot source code   
I just checked. Diskboot is not published on the F27 svn server. Not sure why. -ad

Re: diskboot source code   
I'm not sure what the process is for publishing code that isnt current published. But i've emailed the powers-that-be. -

RE: diskboot source code   
I believe the best way to facilitate and expedite this is to contact
your QNX sales representative.

Re: RE: diskboot source code   
Hi,

There are several computers running QNX 6.2.1 (Patch B) and now we have to replace HDD in every node.

As we know there is a 'lba48' parametr but this option is disabled by default in the devb-eide.

For larger disks IDE/ATA driver must be started as follows:
devb-eide ... eide master=lba48=on
or
devb-eide ... eide...,master=lba48=on

-------------------------------------
By default diskboot starts devb-eide with the following parameters:
devb-eide blk auto=partition dos exe=all cam quiet

and:
devb-eide blk auto=partition dos exe=all cam quiet eide nobmstr ...
if we pass any option to the devb-eide.

For example if I call diskboot in this way:
diskboot ... -o"devb-eide,eide master=lba48=on"
then we get:
devb-eide blk auto=partition dos exe=all cam quiet eide nobmstr eide master=lba48=on

or:
diskboot ... -o"devb-eide,,master=lba48=on"
then we get:
devb-eide blk auto=partition dos exe=all cam quiet eide nobmstr ,master=lba48=on

In both cases HDD size is not recognized properly due to space after "nobmstr".

Am I doing something wrong ?

I know that QNX 6.2.1 is quite old...
... but maybe somebody can modify diskboot.

It is enough to remove "eide nobmstr " or space after nobmstr from it.
 
Regards,
Jacek

Re: diskboot source code   
You could always write a devb-eide launcher and name it devb-eide.  It 
could manipulate command-line arguments passed in (as needed) then 
exec() into the real devb-eide (which you will rename to devb-eide.real 
or something).  It's not ideal, but at least it's simple and doesn't 
require you to modify diskboot.

Re: diskboot source code   
If you're going to that extent, why not simply eliminate diskboot 
altogether?

I definitely can't argue with that. :)
