In S20sendsigs the command being issued is killall5 -18 $OMITPIDS. If
I issue the command killall5 --help I get the message that killall5
only supports 1 parameter, so how does killall5 -18 $OMITPIDS actually

Sorry, I didn't think this was relevant because the support forums say
that in a lot of situations Win XP drivers work fine in Vista and Win 7.
In the case of the wireless network card I use, the microsoft supplied
drivers from Win 7 updates don't work probably because they appear to
have been written 12 months before Win 7 was released. The support
forums say for that wireless card to use the Win XP drivers for the
specific chipset in the card, not the drivers for the card.

Not as I understand things. It is my understanding the first thing the
driver is going to do is ask the device what it is, then ask what it
supports, then set itself up accordingly, possibly also setting states
in the hardware for how it wants to run according to the features its
supplies. I thought my soundcard was a SoundBlaster Audigy LE, but
Ubuntu and Mandriva are both treating is as a SoundBlaster Audigy SE, so
what I think is happening is that at shutdown Mandriva is setting the
card back to the "factory defaults" whereas Ubuntu is not, which is
where I think the problem is. I will also need to check what Win 7
thinks the device is, assuming Win 7 gives me that detail.
