checking kernel options

[Stephen Anthony]

Hi All,

I recently spun a 2.4.20 kernel and absent-mindedly forgot to add
fat/dos filesystem support. When I went to mount fd0, I got a "not a
support filesystem" error. 

No problem, says I. I'll respin with the support. So, using xconfig, I
made sure I had the support selected for fat, msdos, umsdos and vfat;
not as modules, but compiled-in support. Recompiled and booted new
kernel. 

But I still get the same error when I try mounting fd0.

Anyway I can confirm the support is compiled into the kernel? 

Or am I missing something else?
