... but, just so the thread remembers, the pccard is "Zcomax XI-325H 200mW"
... or "SMC2532W-B EliteConnect 200mW Wireless Adapter".

... prism2_srec is compiled from the same CVS source.
... PRISM2_NON_VOLATILE_DOWNLOAD uncommented.
... "tail -f /var/log/dmesg" doesn't show anything...
... dmesg | less  ...shows more! (oops!)

Ahh!
... so the nonDestructive RAM firmware load actually goes like this:
	[firmware]# prism2_srec -gs wlan0 ak010104.hex
	[firmware]# prism2_srec -gp wlan0 ak010104.hex
	[firmware]# prism2_srec -rp wlan0 rf010800.hex

... and then you get ...
	[firmware]# hostap_diag wlan0
	Host AP driver diagnostics information for 'wlan0'

	NICID: id=0x800c v1.0.0 (PRISM II (2.5) PCMCIA (SST parallel flash))
	PRIID: id=0x0015 v1.1.4
	STAID: id=0x001f v1.8.0 (station firmware)

... kewl ...

... If I do a RAM download then I should be able to do:
	[firmware]# rmmod hostap_cs
	[firmware]# rmmod hostap
	[firmware]# cardctl eject 0
	[firmware]# cardctl insert 0
... and prism2_srec again right? yup, that works.

How do I "prism2_srec -f" to avoid having to load RAM when I bring the
pccard up again?  ..or should I _not_?

	[firmware]# prism2_srec -vf wlan0 pk010101.hex sf010800.hex

... generates the following dmesg output after pccard reinsert ...
	prism2_download: dl_cmd=3 start_addr=0x00000000 num_areas=5
	wifi0: Could not read download buffer parameters

... still no go.  maybe my pccard is write protected?  should I drill a
hole in the corner to write enable?!? LOL.

Thanks for being so patient while I'm grokking HostAP..
