Oh, it's easy enough to catch my errors. It happens all too often
when I'm lazy or in a rush. Also when I don't bother to check all the
details or rely on my rapidly failing memory. I may have a Dell CPi
233MHz in the pile somewhere. It died long ago thanks to a fried
motherboard. I could swear that a 32 bit card did't fit, but I'm
apparently wrong. I'll double check if I find it.

I stand corrected. (I just hate it when that happens).

I've run XP on machines with 128MBytes just to see what happens. It
was a painful experience which I don't want to repeat.

Impressive collection of AP's. I wish I had the time. One of "my
never have time to finish" projects is a 2.4GHz direction finder. It
should be an interesting addition to the war driving arsenal.
The AR5213 seems to be one of the chips where most of the processing
was moved back into hardware. Kinda hard to tell for sure from the
description.
<http://www.atheros.com/pt/AR5004GBulletin.htm>
"A single driver and firmware code base supports all Atheros
chipsets, and provides both backward and forward compatibility
with Atheros previous and next-generation multi-standard designs."
If that's true, then there's not much the driver has to do as all the
hard stuff is done on the chip. That also makes it suitable for
underpowered CPU's. Built in PC Card interface so I guess that's
supported.

Thanks for the correction.
