Hi there:

I just upgraded my old ISA IDE controller to
a VLB cache version. Since I need to routinely
compile program with library size up to 2MB,
I was expecting the cache controller would give me some
speed improvement while doing 'ar' and 'ranlib' repeatedly
on the same library. However, after some thorough test, 
I notice that the cache controller doesn't seem to improve
the I/O performance at all.

Does Netbsd support VLB cache controller ? or I need some kind
of driver ? Or does cache controller help at all?

Any help would be appreciated

P.S. I am using 0.8 with my 486 DX2 machine.
with 4MB RAM installed on the cache IDE controller
