Well I found it in Slitaz.
The Slitaz people have done what I thought was impossible... a fully functional os in a 30 mg iso!
I installed Slitaz natively to see if it could live up to my hopes and dreams.
In about 20 minutes I was running firefox with java support, flashplayer support, full graphics driver support, and ready to rock!
Then I installed virtualbox and ran windows xp from a vbox hd file i had created earlier...
I am totally impressed with Slitaz,
It's my newest weapon in my arsenal of computer repair as well.
With very quick boot times and the ability to read and write to ntfs, I use it to fix Windows PC's.
I give Slitaz 10 out of 10 stars!
