You have quite a bit of reading to do.
For starters, you have a TSOP flash, not a softmod.
Second off, you should just be able to make an evox boot disc yourself (take the evoxdash.xbe, rename it to default.xbe, and put it on a CD along with the evox.ini file. Put a/some dummy file(s) on the CD just to be safe). If somehow, this is too much for you, go download Slayers 2.6, which is an evox boot disc/auto installer.
Finally, make sure your Xbox's DVD drive can actually read CD-R's, or better yet, use a CD-RW, which can be read by pretty much all Xbox DVD drives.
