Hi Andrew,

Well I did manage to test your 2.2 patchlevel 2 8029 driver!

Realise now that ramdrive to ramdrive transfers via LAN, at least with 
the RAMFS64 version I'm using, far from giving optimal speeds are 
exactly the opposite!

I have passed you a personal copy of this message with a zipped 
attachment detailing all the results I achieved and cross-referenced to 
the OS version/RAM/disks used and formats on them/ cable-lengths/cache 
in use etc.

I'm sorry it took me so long to respond, but I unfortunately jumped into 
the testing "boots and all", and didn't give any thought to actually 
making the output useful, and easy to interpret.  This is what has taken 
the time - poor advance planning [none!].

Hope this information will be useful.  Speeds were similar to yours, and 
a single TRAP occurred, on the receiving machine whilst transferring to 
a RAMFS64 drive, but it may have been coincidental.

For others who may be interested, this is how I eventually formatted the 
extract of the full data, by hand!
