Ok, I took a closer look at your mount list, and found a few odd things
(my entries are below yours):

> SizeBlock : 128 
BytesperBlock = 512

Howcome the half sized data blocks? This will slow you down some.

> MaxTransfer : 131072 
MaxTransfer = 130560

You'll be a little safer to drop this down to 130560 to prevent possible
problems.

> Mask : 0x0fe
Mask = 0xfffffe

This looks like you are restricing DMA into a tiny little bit of Chip
RAM. No wonder things are slow! If you fix this, things will be a LOT
faster.


Here's what the latest version of RDPrep reports for my Q105. There's a
lot of difference between yours & mine, so I'd guess your running an old
version. The new RDPrep with the graphic interface is well worth the
upgrade fee.
