I just finished installing xDSL on my Xbox just a few minutes ago. I thought I would do the install like I would on my computers, using all the space available. Now I can't install Flash or Java. Says I don't have the room. Is it possible to resize it, or do I just need to delete everything for it, and reinstall? Any and all help is greatly appreciated.

what type of install did you use? if you just copied the files over, then you have a frugal install, which is read only.
if you booted up XDSL then chose a type of hard drive install, either loopback aka FatX, or native.
explain your situation more.

It's a loopback install.

double check that your linuxboot.cfg points to your loopback file. it should be at E:\xdslfs or F:\xdslfs.
also, how much space did you let it have? i think that java needed like 200mb or something like that.
if all else fails, just try to install again.

Well, I guess I'll just reinstall it. Anything special I need to know to reinstall?

Also, for my internet, I'm using an extra router as a wireless repeater for my connection. How, in xDSL, do I connect to it?

if your going to reinstall, use as much filespace as you can. i use 2gb which is the max, but if you think about it, regular linux distros use 5-10gb for a fresh install. if you can, you should upgrade your hard drive.
as for the internet connection, i don't really understand you. for the xbox, as long as a cat-5 cable is plugged into the back, the xbox will connect to that line. so if internet is a problem, you need to tweak your router, not xdsl.

Ok. I figured out I had bricked my router. Fixed it now, so I shouldn't have a problem. Thanks.
