Hi all,

Cisco PIX is not IOS.  The operating system was developed for the PIX, it 
is solely PIX OS.  The PIX development group used OpenBSD as a reference 
implementation for protocol support, so this has led to rumors that the PIX 
is *BSD based.  It is not BSD based.

The PIX does have an X86 motherboard.  However the PIX OS installed on the 
flash does not provide support for video, or any additional devices.  So, 
if you really wanted to, you could remove the PIX OS flash device, install 
a video card, keyboard, disk drive, etc, and have a PC on which you could 
load any old OS you wanted.  Not recommended, and would possibly void your 
product warranty.

Thanks much,

Lisa Napier
