Hacking my Lifedrive

WOw ,just read this thread in 1src forums about the Lifedrive CF hack and I find it amazing what it can do to ones Lifedrive.. I am planning to do this hack and I’ll probably document it here.

I had just recently bought a gps receiver for my lifedrive and I find that the lag is unacceptable for GPS . I hope this hack will solve that and I also will try to install Tomtom on a SD card that I also just bought. Lets cross our fingers folks!

One small step

Hi! My name is Ralph Bacolod. I’m from the Philippines. I wrote this blog to show my love for Linux.

I first heard of linux back in 1998. I was new to the web then. I was hooked the very first time I surfed the web. But I was dismayed that I was using a very poor OS . Who hasn’t experience the dreaded BSOD (Blue Screen Of Death).

That got me started in my quest. Surely there is something better than this.

I found linux!

My first linux was Redhat. It was easy to install .The hard part was repartitioning the hard disk. This was two years ago. I installed redhat on the computer at work. I got the cd from a guy in our local LUG.

This past weeks got me kinda busy. I was busy surfing the web. I was looking for a cheap laptop I could install linux on. I finally bought one from ebay .I got it for $229. It’s a IBM Thinkpad 770x. I haven’t gotten my hands on it yet. It’s still in the post office. I’m gonna pick it up this monday..

Before this laptop,I was basically squatting for my linux experience. I installed Debian on my girls PC and also my sisters PC.
I also bought books so that I could learn more about linux.

Awesome sound with ChainTech AV-710

Jus t upgraded my soundcard to a Chaintech AV-710. What i like about this card is the digital output,It’s way cooler to connect to my A/V receiver via TOSlink. I now can listen to my favorite internet radio through my receiver,Awesome!

Well,I had to search the net for a decent .asoundrc and I found one that works but It only allows me to connect through digital but not the analog. I want the analog to work coz my pc is in my bedroom and my A/V receiver is in the living room and I want the small speakers in my bedroom to function also.

So I did a little research and I did a little hack to my asoundrc .

Here is the original asoundrc.

I also added this to enable digital passthrough. You’ll need this if you want to watch DVDs and you want to hear Dolby/DTS surround sound. Just paste this to the original asoundrc.

pcm.!iec958 {
type plug
slave.pcm “hw:0,1”
}

I also made some some small tweaks to the asoundrc to allow me to switch outputs from digital to analog.
So this is the final asoundrc.

pcm.!default {
type plug
slave.pcm “dmixer”
}

pcm.dmixer {
type dmix
ipc_key 1024
slave {
pcm “hw:0,0”
format S32_LE
period_time 0
period_size 1024

# increased buffer_size because in my system 1024 cause bad
# audio performance (for totem media player and mplayer)
buffer_size 8096

rate 44100
}
bindings {
0 0
1 1
}
}

ctl.dmixer {
type hw
card 0
device 0
}

pcm.!iec958 {
type plug
slave.pcm “hw:0,1”
}

I just change dmix settings to device 0 instead of 1. So now what i do when I want to listen through my Onkyo 504 A/V receiver is this:

mplayer -ao alsa:device=iec958 *mp3

And If want digital surround Dolby or DTS :

mplayer -ao alsa:device=iec958 -ac hwac3 dvd://

Hope this Helps!

The ones in red are the most important ones coz that will allow you to boot your thinclient via dhcp and nfs.

Big Blue ThinClient with Debian

About a week ago ,I got the IBM Netvista 2200 that I bought from Ebay . I wasn’t expecting it to be that small a thin client . Its just about an inch and a half thick..Anyways, I was planning to setup it up as a diskless client. So I already had a pretty rough idea how a diskless client works.. To sum it up,it gets its kernel from a server and run everything off of that server ..

Well,for a client to boot from the server it must have PXE. Turns out mine doesn’t have it.. so it has to have some other means of booting from a server since it’s a thin client.. to get it to boot one must setup the dhcp server to serve the kernel via NFS since TFTP via PXE doesn’t work ..

I have my Openwrt setup that way ..I’ll post my dnsmasq here next time ..
