How to install Linux on an eMac
Why replace Mac OS X with Linux on an Apple eMac? I did it to revive an aging hardware platform and provide a computer to a friend. Here's how I replaced "Puma" (OS X 10.1) first with Debian, then Ubuntu.
My friend Jack asked me a couple of weeks ago to help him find a good deal on his first computer. He just wanted something he could use to browse the Internet and keep in touch by email over a dial-up connection. I thought of the eMac in my living room, which has done nothing but gather dust the past few years.
The eMac is a fine machine, but it has always been a little slow, due primarily to the fact that it has only 128MB of RAM. That shortage of RAM kept me from upgrading to a later version of OS X several months ago: the latest version would install only on machines with 256MB. I didn't want to give Jack a machine that he would immediately need to spend several hundred dollars on in order to bring its operating system up to snuff, so I decided to see if I could install Linux on it.
There are a number of distributions that support the PowerPC (PPC) architecture Apple used in the eMac. My first choice was the ubiquitous Ubuntu, which offers a "desktop" (live CD) version for PPC machines. I downloaded the ISO and burned a CD, but unfortunately, the desktop version would not install on my eMac. It crashed while booting and I couldn't find any way around it.
My second choice was Debian, which offers a "net install" ISO for PPC architecture. I grabbed it, burned the CD, and in no time at all had a net install in progress, downloading packages from the Internet via the eMac's Airport wireless card.
Everything was fine until my Debian eMac tried to load X and crashed. Fortunately, Google helped me find a replacement for my XF86Config-4 file, and soon I had a working GNOME desktop. Well, a qualified working desktop, at least: I had no right-click ability with my Apple rodent, the eMac's internal modem had not been detected, and there was no sound.
Back to Google for answers. Thanks to those who came before me, I found a solution to the right-click problem. I added the following three lines to /etc/sysctl.conf in order to emulate the center mouse button with the F11 key and the right mouse button with F12:
dev/mac_hid/mouse_button_emulation = 1
dev/mac_hid/mouse_button2_keycode = 87
dev/mac_hid/mouse_button3_keycode = 88
Next came the really hard part: getting the internal modem to work. It has been so hard, in fact, that I still have not found a solution, though I spent a good deal of time looking for one. I learned that the modem Apple used in the eMac is a USB softmodem, and though there are Linux drivers available for some softmodems (a.k.a. Winmodems), I never found one for the eMac's modem.
During my Googling to find fixes for what ailed the Debian install, I came across a reference to an alternative Ubuntu PPC ISO, which was claimed to work even on machines with less than 196MB of RAM. This version of Ubuntu installed where the "desktop" version had failed. X still crashed, but I got past that the same way I had on Debian. Here are the steps I took to do so on Ubuntu:
- Press Alt-Ctl-F1 to start a console session
- Make a backup of /etc/X11/xorg.conf
- Run the command
wget http://homepage.univie.ac.at/georg.koe/XF86Config/XF86Config-4.emac700nvidia.working - Edit the keyboard layout line in the configuration file to change "de" to "en"
- Copy the edited XF86Config-4 file to /etc/X11/xorg.conf
- Restart the machine
Note that on Debian Alt-Ctl-Bksp will give you a command prompt, but on Ubuntu it will simply keep trying to launch X. Also remember to change "de" to your native language in the keyboard configuration.
Ubuntu did not require me to hack /etc/sysctl.conf in order to be able to use F12 for right-click, and the sound on my GNOME desktop "just worked." But I didn't have any more success getting the internal softmodem to work than I had had with Debian, so I decided to do a little hardware hacking and use an external serial modem.
By the way, if someone tells you that all external modems are "hardware" modems instead of softmodems, it's not true. There are a number of crippled USB modems on the market. As far as I know, however, all serial port external modems are true modems.
The problem with using an external serial modem is that the eMac doesn't have a serial port interface. I visited my local Radio Shack and found a serial/USB converter for about $35, and used it to connect a Zoom external modem to the eMac.
The external modem was not autodetected, but one last search on Google provided the missing bit of information I needed to get dial-up working. I needed to tell the GNOME Network tool that the modem lived at /dev/ttyUSB0, and of course provide the phone number, user name, and password for the ISP.
After all this effort, how does it work? It works well, though it is still on the slow side. Another 128MB of RAM would probably make a big impact on performance. Ubuntu looks and sounds good on the eMac. For Jack, at least for the time being, the marriage of Apple hardware and free software will be more than adequate.
SEO Tips on On-Page Optimization
On-page SEO or search engine optimization refers to changes that you can make on your web page to increase the chances of it being displayed in the top 30 results for a particular search term or search phrase.
Many people think that SEO is something complicated and difficult to implement. However, like many things in life, SEO is common sense - your job is to provide what the search engines want.
On-page optimization is quite simple and relatively easy to do. Let me show you some simple tactics that will help you to get your web pages visible in the search engines by focusing on 2 very important on-page factors.
HTML Tags
Textual Content
Search Engines Love Text
Search engines want fresh, unique content - textual content. Because, text can be interpreted by simple algorithm whereas technology to interpret pictures, video and music is too expensive and require excessive computing power.
Search engines love text. Textual content is known to be the “spider food”.
If you want the search engine spiders to crawl your website every day, make sure that you have plenty of good textual content and keep your website fresh by adding unique content several times a day.
HTML Optimization
Once upon a time, all you need to do to get into top ranking was to add the tag. Please do not worry too much about this meta tag now. Google, Yahoo, Live(MSN) and Ask simply ignore this meta tag when it comes to search engine ranking algorithm.
The important tags are the
Hide Users on the Welcome Screen
When you add an account for certain users with Windows XP, their user names will appear on the Welcome Screen. Sometimes a user needs to be added to a Windows XP machine, because the user needs access (via the network) to resources on the machine, but the user will not be physically logging in on the computer. You can remove this user name from the Welcome Screen, while still maintaining the user account.
1. Start the Registry Editor
2. Go to HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon \ SpecialAccounts \ UserList \
3. Right-click an empty space in the right pane and select New > DWORD Value
4. Name the new value exactly as the Username
5. Leave the Value data as 0
6. If you want to enable this user again on the Welcome Screen, either double-click the Username value, and change the Value data to 1, or delete the Username
7. Close the registry editor
Mac TCP/IP setup
First we need to create a new configuration for the proxy.
Click on Apple Menu, select Control Panels, select TCP/IP. This will open the TCP/IP control panel.
Go to the File menu and select Configurations.
Select one of the present configurations, click on the Duplicate button, name the Duplicate configuration "Proxy", and click on OK to create the new configuration.
Click on the new configuration ("Proxy") to highlight it as shown below, and click the Make Active button.
Change the settings in the TCP/IP control panel window until they match the ones shown below.
IMPORTANT! To get a dialog box like the one below, the User Mode will need to be set to "Advanced" or "Administration". (Do this by going to the Edit menu, selecting User Mode, and clicking on the Advanced or Administration radio button.)
NOTE! The IP number will change depending on which Client computer you are setting up. If you have only one Client computer, set it to 192.168.0.2 as shown below.
If you are setting up the second NIC in the Sharing computer, set the IP address to 192.168.0.1.
NOTE: Make sure you select the correct Ethernet card when setting the IP address. The MacOS doesn't display any information about the Manufacturer of the card in the TCP/IP Control Panel. It just identifies the card by Slot Number. So you may have to experiment with the settings or try to read the Slot Number information on the Mac motherboard to determine which card is which.
Click on the Options... button. Select Active and make sure the Load only when needed box is unchecked. Click OK to close the dialog box.
Quit the Control Panel. Your TCP/IP is now set up.
Enable root password ON MACOSX
This is the easiest method to enable the "root" account on a Mac if you are more of a GUI person:

- Start the NetInfo Manager application, which is in the Application/Utilities folder: Macintosh HD -> Applications -> Utilities -> NetInfo Manager.
- From the top menu bar pull down the "Security" item and select "Enable root user". You will have to enter the administrator's password to authenticate yourself.
