HAIKU OS challenge

HAIKU OS challenge on my Compaq Presario CQ56

I am writing this on my "resurrected" PowerBook G4 Titanium A1025. This resurrection required slightly disassembling the bottom lid and taking the broken IDE HDD out and putting an mSATA SSD placed inside an IDE - mSATA converter in 2.5-inch format in place. I don't see any dramatic performance improvement but it works now.

I have tried HAIKU OS on HP Pro 3120 for a while before it broke (or suddenly it ceased to start up) in 2019 and part of 2020. It was a revisit for me.

Back in early 2000's when I was about to leave Japan for Germany, I had BeOS on one of my PCs. It was a preview release of BeOS but the expected official release never took place (or did it?). Jean-Louis Gassée could not sell this operating system to Apple at that time. Apple bought NeXT computer bringing its CEO Steve Jobs back to Apple.

Anyway, When this HP Pro 3120 ceased to boot, I bought a used Dell Optiplex 780. I did not install Haiku on it.

Haiku was practical. It had almost everything I needed. Nice browsers (although not so perfect), An office suite (LibreOffice), video players and Japanese input system that works.

It does not work on my Compaq Presario CQ56 for some reasons. I tried the Beta 2 and did not work. This time I tried Beta 3 and it did not work. The booting process falls into the debug shell in the middle of the process.

A1025 is now resurrected

I put an SSD purchased from Amazon Germany a Chinese brand 128 GB mSATA SSD. I had a couple of 2.5 inch form factor IDE - mSATA converter and I used one of them. Luckily the PowerBook G4 series laptops (notebooks) have easier access to the HDD bay. Just unscrew the screws and open up the bottom lid and voila! you have the HDD right in front of you.

I did and now it is working.

Actually, I needed several hours before it became operational.

In essence, the mistake that I made was not taking a good look at the erasing (formatting the disk device for the first time) the SSD after the installation. There are three kinds of formatting schemes. One of them is Apple Partition Map (APM) format. It is the format you have to choose if you want the disk device to be the booting device.

I was not careful about the format and it was formatted as GUID.

Obviously A1025 did not boot from the SSD installed inside until I corrected the mistake.

Now it is fully operational. It is running Sorbet Leopard.

As a side note, I have to report that I don't see any particular performance improvements after the SSD installation sadly. I think a bottleneck is the key to my plight.

The SSD is faster than an typical HDD but the communicating speed inside PowerBook G4 is the old IDE connection, which is quite slow itself.

Important thing is that my A1025 is now working.

The Matrix 4 Resurrections 2021

I am excited. I own all the Matrix series DVD discs with me. The first one was purchased back in the 90's when I was still living in Japan. The second and the third ones were purchased in Germany, I believe.

Back in late 90's when the first installation came out, the idea of virtual reality, the idea of computer simulation and others were not so widely understood. Now the World has caught up with the ideas behind the movie.

A1025 (PowerBook G4 Titanium)が復活した話

A1025 Two（つまり2号機）の内蔵ハードディスクが壊れたのが、２週間程前だったかな。そして、今日復活させた。最近アマゾン（独）から購入したmSATAをIDE 2.5" - mSATA変換器につめて、それをA1025に詰め込んだ。

その後、ターゲットディスクモードにして、外部から以前にこの事態（HDDの故障等）に備えて保存しておいたディスクイメージ（Sorbet Leopardに必要なソフトを入れて設定した状態）からレストアした。この際にちょっとした不手際があり、しばらく悪戦苦闘したのは秘密です。

ディスクのフォーマットがGUIDになってしまったのに気づかずに、レストアしてしまい、そのディスクから起動できないという事態になりました。その不手際に気づくのに時間が掛かり、半日無駄にしました。APM（アップル・パーティション・マップ）に戻してフォーマットし直して、無事に復活しました。

早速、現在これを書いてるのはその復活したA1025 Twoです。

ですが、その後A1134 iBook G4に切り替えて、書き続けてます。こちらも健在です。手元のA1054の（Early 2002だったかな）iBook G4 12インチ（1 GHz）も復活させてあげたいのですが、分解が面倒なので果たせてません。

分解してHDDベイにたどり着くのた大変なんです（汗）。

マトリックス４ Resurrections

早く観たいですね。第一作からのファンです。第一作が出た時は日本に住んでました。当時はWindows98とかWindows2000とかのマシンを持ってたし、Slackware Linuxも使ってました。古いMacも持っててジャンク品で入手可能なものが当時のHard Offとかであったので、複数入手して悦に入ってました。

当時のハードウエアではDVD再生はかなり難しく、最新のCPUだとソフトウエア再生もできましたが、古めのCPUの機器だと専用のデコーダーボードが利用できました。実はそんなハードウエアデコーダーボードを入手して（中古だったかな？）古い機種（確かAMDのIntel MMX対抗品だったと思う）でこのMatrixの第一作を再生してました。後に自作したAthlon 1 GHz（オーバークロックして1.2で使ってたかな？）だとソフトウエアでコードで再生できたような記憶があります。確かじゃありません。

そんなファンです。

今回の副題のResurrectionsですが、復活ですね。前作の最後で主人公のネオは死んでます。一応現実の世界で死んでますね。今回は復活する訳ですね。楽しみです。
