The netinst CD page at debian.org
On the page http://www.debian.org/CD/netinst you have the section "What
types of network connections are supported?" where you say "Internal (PCI)
ISDN cards and WLAN cards are not supported - sorry!" it is unclear whether
"These cards are not supported for installation, but work fine after you've
installed the right software."
"These cards don't work with Debian, so if you want them to work look
somewhere else or write the software to make them work".
I suspect that the former is the case, but as a newbie could well end up on
that page it might be something to dis-ambiguate.
Thanks for the great OS!
