Dear Friends,

I am interested in boot code(BIOS) of Genesi's PegasosPPC. I like to know more about the OS loader and the
vt8231(south bridge) initialization code.
I heard Pegasos followed open firmware standards.
If code is available please provide me the pointer for the
SmartFirmware.

Thanks in advance.

Regards,
Suresh Chandra Mannava

Hi Suresh, we have your email too. We will answer you directly and also post some links here. Have a look:

http://www.genesippc.com/of_presentation.php

We will be updating this to include support for IBM, Marvell and Themis. We are also looking into support for other Power.org members and even alternate ISAs.

http://www.pegasosppc.com/support.php#ofmanuals

You can find Firmware Manual links on that page.

There is also useful information on this site here:

We look forward to your interest!

thanks for that info.

I got Genesi schematics from power.org
I am interested in firmware part of it.
implementation of AGP connector from Marvell chip and interface of VT8231(basically intel hardware) facinates me.

I am searching for the firmware(BIOS) code for the same. Hope Genisi will release it as open source.

Is there any open source BIOS available for the same.

Regards,
Suresh Chandra Mannava

Hi Suresh, we will not be releasing the sources to the HAL/OF for a couple of reasons. First, we are building a business from licensing it and second because we want to manage it to insure interoperablity between platforms using it.

Do not let our direction slow you down! IEEE1275 is a standard and there are many open solutions being developed.

R&B

2 digitalsuresh:

What do you want to know and to do? I think i can help you with some information. I was playing enough with ISA subsystem of the Pegasos, i've coded enhanced support for parallel port in Linux and floppy drive in Linux and MorphOS. Also i am trying to write a set of software which would allow to run MacOS X natively on the Pegasos, currently it consists of heavily modified BootX bootloader which is ~70% finished.

you have coded floppy support for MorphOS ???

to sonic,

Hi, I am interested in VT8231 (south bridge) part. I think some open source boot loader should exist.

Bootloaders don't need to be aware of hardware initialisation (unless you're doing something fairly specialist). openfirmware provides for that.

yaboot is an opensource bootloader for openfirmware and can be found here: http://yaboot.ozlabs.org/.

If you're referring to opensource firmware, then you might want to look at http://u-boot.sourceforge.net/. I've seen it used on a number of powerpc and arm boards, but it supports other architectures as well. It's mostly geared towards embedded platforms, so I assume it doesn't contain much by way of controller initialisation.

I am talking about u-boot type of bootloader. It does basic hardware initilization and a loader to load linux/vxworks OS.

A code like u-boot should initializes peripherals like Marvell system controller and Vt8231.

Yes. It currently perfectly works in ReadOnly mode, writing is still broken. I can't upload it and don't know when i'll be able to. I can't bring any removable media to my work.
