PowerMac G4/1Ghz with Nvidia GeForce 440mx notes

Just a few notes for OpenFirmware, Xorg configuration. Sources guide-open-firmware-apple-bios-0, xorgconf-powermac-g41ghz-geforce-4-mx-apple-studio-display-17, http://sowerbutts.com/linux-mac-mini/.

OpenFirmware:

• ls - displays contents of the current path in the device tree.
• devalias - provides a list of short alias names for key hardware devices.
• .properties - provides a list of properties for the selected device.
• pwd - displays the current path within the device tree.
• dev - selects a device (using either the alias or absolute/relative device tree path).
• words - provides a list of forth scripts associated with the selected device.
• source - executes a particular forth script.
• load - loads a image from disk, cd, network or another device.
• go - execites the currently loaded image.
• see - displays the source code for a particular forth script.

Booting installation of Debian GNU/Linux Squeeze 6.0 on PowerMac G4/1Ghz: 

0>boot cd:,\install\yaboot

 Partition disk:

1. Don't touch the small Partition #1 at the start of the disk, that contains the partition map itself.
2. Partition #2 (16MB) is for "yaboot", the bootstrap that allows you to boot
3. Linux or MacOS. You want to tell the partitioner to use that partition as a "NewWorld boot partition", and set the bootable flag.
4. Partition #3 (2.0GB) should be used as "swap area".
5. Partition #4 (48.0GB) is your root filesystem, you want to use that as a "ReiserFS journalling file system", format it, and mount it on "/"

 Booting after installation:

0>setenv boot-file hd:3,\yaboot

Изложба на Иван Христов - Грога, 15.12.2011 - галерия Аспект - Пловдив

На 15.12.2011г. габровският художник Иван Христов - Грога (всъщност това е баща ми) открива самостоятелна изложба в Пловдив - галерия "Аспект", площад "Стефан Стамболов" 1А (до общината). Откриването е между 16:00 - 20:00 часа.

За повече информация може да посетите сайта му http://groga.gabrovo.com/ а също така и на facebook страницата му: http://www.facebook.com/...

Втори и трети опит за домашна бира.

След успеха на първият опит си поръчах още 2 кита. Правих ги един след друг с разлика няколко дена. Изборът ми се спря на Multons Premium Bitter (светла) и Midland Mild Ale (тъмна).

Ферментацията става по вече описания от мен начин. Важно е просто да се спазват инструкциите.

Midland Mild Ale - до момента на мен не ми беше харесвала тъмна бира. Пробвал съм почти всички които ги има на пазара (за бутилираните говоря) но така и не повторих. Тази мога да кажа че беше супер без никакви забележки. Трябва да отблежа че не харесвам много горчиви бири а това е Ейл който по принцип трябва да е сладникав.

Premium Bitter - това трябва да е типичен английски битер и може би за това на мен не ми хареса. Прекалено ми е горчива. От друга страна родителите ми много я харесаха от което следва че всичко е до въпрос на вкус. Просто трябва да се пробва.

Следващото което ще тествам е пак на Muntons Export Pilsner.

Fix console font on NetBSD 5.1/macppc

One of annoying things about booting NetBSD 5.1 on PowerMAC G4 after install is console font which is too big to fit in screen. Today I found solution on port-macppc mailing list. You can see it here http://mail-index.netbsd.org/port-macppc/2011/10/18/msg001479.html.

Edit your kernel config file to look like this:

#options    FONT_GALLANT12x22
options       FONT_VT8x8

then recompile and reboot.

Webkit-gtk on NetBSD 5.1/macppc additional notes (solved)

I've got response from bug report on webkit-gtk (pkg/45429) and here is solution for fixing compiling process on NetBSD/macppc. Create a file named hacks.mk in pkgsrc/www/webkit-gtk. Copy/paste the following and then do make clean; make.

NetBSD 5.1 pkgsrc webkit-gtk compiling problem on PowerMAC G4

After successful installation I've got working NetBSD 5.1/macppc and I tried to add some pkgs to use the MAC for workstation. Here what I've got:

Trying to compile some meta-pkgs like gnome or kde I ran into some problems.

webkit-gtk - Compilation fails on some file FastMalloc.cpp but all errors are redirected to /dev/null so I couldn't find how to fix this. There is also bug report from 2009 about this problem you can see it here http://mail-index.netbsd.org/pkgsrc-bugs/2009/02/01/msg030663.html. Here is the error I've got:

Still no solution which means that kde web browser and epiphany web browser will not be build. After 1-2 days searching on the net for solution I decided to solve the problem myself. After some tweaking of the GNUmakefile I finally got the error message that fails the compile process

Quick search over google and I found that there was such problem with compilation of webkit-gtk on other OS's on PowerPC arch. It seems that this is gcc compiler bug on macppc arch. Simple solution is to compile with -O0 (do not optimize) instead of -O2 option.

Just for now here is quick and dirty solution to this:
start building process and when GNUmakefile is generated stop the process with ctrl+c.
Now open generated GNUmakefile (usually in webkit-gtk/work/webkit-gtk-1.4.x/GNUmakefile) with some editor and replace all -O2 with -O0 then save and exit and continue the compilation process by entering the dir and typing: gmake


Here are some links for the solutions Í found:
debian solution - http://blog.gmane.org/gmane.linux.debian.ports.powerpc/month=20070801/page=8
webkit-gtk bug report - https://bugs.webkit.org/show_bug.cgi?id=14521
bug report to gcc - http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10396

Unfortunately these solutions dont work on NetBSD and I'm not good enough with assembler to make myself a patch.

When this was fixed I ran into another error.

This can be fixed easy by upgrading your gettext package. cd pkgsrc/devel/gettext; make install
