I just tried out Grey Cat linux.
Downloaded it from
http://www.pcpages.com/greyclinux/
Unpacked the files to C: and ran the hdinst.bat
Rebooted into DOS and started it with linux.bat in the Linux directory.
Logged in as root, used the linux commands cd.. and ls to see what directories there are.
Went to usr and into bin, started mc which is a norton commander clone.
So it works, but at a low level, console mode, I have not found a really modern GUI system in it yet.
It is good for a first look at how linux works, just like winlinux but a lot smaller and easier to install.
There are basically two ways to get to know linux.
1: From a modern GUI perspective, using a live-cd like Knoppix, or Mandrake live, or Suse.
2: From a low level console mode, using a umsdos system like Dragon linux or Grey Cat.
The modern GUI way is best for people who want something that works, so you can start reading mail, use usenet, listen to
mp3s, paint pictures, etc.
But sooner or later you need to know more about how linux works technically, and then you need the low level knowledge you can
get with an umsdos system, for example.
