PXE-E51 No DHCP server

Im attempting to install Windows 7 in my Netbook (Asus 1005HA) from my Notebook (Asus N53JF) using TFTPBOOT.
I was getting the error "PXE-E51 No DHCP server" after setting up the TFTPBOOT following this guide.
Finally i found out that increasing the timeout in the settings from 3 secconds to 15 solved the issue.

On behalf of the "NPSWF32\" and "RipForGames.bat Not Found" problem

My solution to this problem was to execute the following line in CMD:
"takeown /f C:\Windows\winsxs /r /d y"
In order to be able to modify the permission of the Administrators group so the setup would work correctly.
After running the line and waiting for it to finish, head over to the C:\Windows\winsxs folder, right click it and select propertires -> security -> advanced. Locate the Administrators group and double click it in order to give it Full Control. Apply changes and then run the setup.exe
My windows (win7) reported the process to be hanged up, but "waiting for program to respond" worked for me.
You might want to change the security policy to default after installing

Just Cause 2 & Airfoil

Just wanted to make a quick post mentioning that Rouge Amoeba's Airfoil, with the Instant Jack enabled, will crash Just Cause 2 on launch. Disabling the Instant Jack should stop this behavior.

Disable Poweroff when lid is closed in Xandros Presto!

1) Press alt+f2
2) Run nothing (empty text box) with the "Run in Terminal" box
3) type in this:

This will make the script that executes when the lid button is pressed unexecutable, thus not turning your computer off when you close the lid

Disable Trial Limit in Xandros Presto!

In this tutorial i will teach you how to disable the trial limit in Xandros Presto!

1) Boot up your Xandros Presto! It must be one that still has trial period remaining (You can change the BIOS date to fool it)
2) Press Alt+F2 and click the Run In Terminal, and click Run (the textbox must be empty)
3) Now you have a working Terminal window, type in this:

sudo chmod -x /opt/xandros/bin/PrestoLicenseManager

Now your License Manager will be un-executable, and wont run anymore and block the rest of your OS.

OSX server, Wiki and Active Directory

I had a lot of issues enabling a wiki service with a OSX server in a Active Directory enviroment.
Given the case you have an Active Directory with all the authentications (users, groups, etc) and you want to implement a OSX wiki server, It wont be an easy feat.

This is what I did:

1) I began with a clean install of the OSX Server, and configured it to be a Open Directory Master.
2) Then, I binded the OSX with the Active Directory, and added the AD to the search and auth. policy
3) With the WorkGroup Manager, in OSX, I created a workgroup with the users I want to allow to use the wiki, and gave it permission to use the Wiki resource.
4) Using the Workgroup's MemberList, I clicked on the + simbol, selected Active Directory from the little globe icon over the list, and drag and dropped the users from the AD I wanted to have wiki access
5) Saved and closed the WorkGroup Manager, opened the Server Admin.
6) Added iCal and Web services to the list, then turned iCal on (should get up automatically) and turned on the Wiki service on the web, then started the web.
7) Then you must follow this procedure: Apple Support TS1619
8) Wait a minute or two, then access your webpage using the domain you gave the web page (Will give 404 error when trying to access the wiki group if you don't) and you should be able to authenticate using the Active Directory users you added to the workgroup

Bash Script for Muting front Speaker

The following script will evaluate your "Speaker" audio output and change it to 0% or 100%, without modifying any other output.
This can be used to play audio from your speakers and your headphone output at the same time, or to roughly work-around the issue affecting some laptops where the speaker doesnt mute when a headphone is plugged (AKA jacksens not working)
It requires Alsamixer

export i=`amixer sget Speaker | grep 'Front Left:' | cut -d'%' -f1 | rev | cut -d'[' -f1`
if [ $i -eq 0 ]
then
amixer sset Speaker 100
else
amixer sset Speaker 0
fi

The script works by getting the amixer output for "Speaker" (you might need to change that); chopping it untill only a value is remaining (hence the cut | rev | cut); evaluating the output and then setting the volume to 100% or 0%

If this does not work you might need to change the Speaker output for some other, you can find your output's names by entering

amixer

in the terminal, and then changing any occurence of Speaker for your desired output's name.
