graf_chokolo: OtherOS is Back! - 改機

http://grafchokolo.com/ps3-development-page.html/comment-page-10/#comment-3844

接續昨天說的，graf_chokolo釋出下面的工具，讓使用者能在3.41以及3.55版韌
體上直接安裝 Linux。

otheros-utils/common.git
otheros-utils/create_vflash5.git
otheros-utils/create_vflash7.git
otheros-utils/delete_vflash5.git
otheros-utils/delete_vflash7.git
otheros-utils/install_otheros_bootloader_loader.git
otheros-utils/install_petitboot_on_vflash5.git
otheros-utils/panic1.git
otheros-utils/resize_vflash.git
otheros-utils/udp_printf_client.git

原始碼是3.41版專用的，使用前必須要先對HV Call 114 進行修補，如此才能允
許GameOS存取HV區段藉以載入petitboot 。

3.55版要安裝則需要要配合修正 http://pastie.org/1778085

操作順序是：

HOWTO
=====

1. Start my udp_client_printf on a PC to see debug messages which are
sent as UDP broadcast
2. Use delete_vflash5, it removes VFLASH region 5
3. Run create_vflash5 to create VFLASH 5 region again but now larger
4. Run resize_vflash to add 40GB to your VFLASH where Linux can be
installed. Warning: All data on HDD will get lost, so make a backup
You can modify my source code if you want to set different VFLASH size.
5. Reboot GameOS, it will reformat HDD but won't touch newly added
40GB to VFLASH
6. Run create_vflash7 which creates new VFLASH region of size 40GB.
You can modify my program to set different size.
7. Place dtbImage.ps3.bin on USB stick, plug in and run
install_petitboot_on_vflash5

The following steps are temporary and only for testing for now till i
make a custom HV with dual boot:

1. Run install_otheros_bootloader_loader
2. Run Panic1

And you should see petitboot.

Here is my petitboot which supports VFLASH storage device:
http://www.sendspace.com/file/k04pch

It has all tools you need to install a Linux, e.g. wget, kexec, fdisk,
telnet, ssh, ...

You can connect to a running petitboot from your PC using telnet or
ssh. My petitboot uses DHCP so it will get an IP automatically.
I used telnet to connect to petitboot and installed my gentoo remotely.

I used petitboot directly to install gentoo on VFLASH.

The VFLASH region 7 is /dev/ps3vflashh on Linux. Use e.g. fdisk to
partition it.

And make sure you create as first partition a 100MB boot partition. If
you do so you will be able to use some nice features of my HV later
Do not install anything on it.

I created 4 partitions on my VFLASH region 7:
- 100MB boot partition for later use
- 2GB swap space
- about 20GB for gentoo
- about 20GB for Debian

Here is the HOWTO which i followed in order to install gentoo:
http://www.gentoo.org/doc/en/handbook/handbook-ppc.xml

I myself tested everything on PS3 3.41 only. I do not intend to use
3.55. With every new OFW SONY removes more features, so why should i
use 3.55.

But you can adjust my programs for 3.55.

If you encounter any problems then contact me and i will try to help
you.

******

要還原的話也得先備份硬碟資料，然後在外接裝置安裝一個 Linux系統，並使用
graf_chokolo的核心，最後將/dev/ps3sda 的磁碟分割表還原。

重新開機後系統會提示重新格式化硬碟，格式化完成後就反安裝成功了，原先分
配給 Linux的VFLASH region #7也會還給GameOS。
