How to use
!!!!!!!!!!!!!!!!!!!!!!!
It works only on x86 (32bit mode) CPU with linux
I don't think there is any real chance to compile on windows
!!!!!!!!!!!!!!!!!!!!!!!

I. Compile from source, use this only if you know what you are doing,
otherwise, try compiled version.
Required - gcc3.4 - qemu is not compatible with gcc 4.x, so you will need
3.x.
1. Edit Make file, and customize line: 
TUNE_FLAGS=-march=pentium3 -mtune=pentium3
with whatever CPU you have (type man gcc to see possible types)
This is only for optimization! It won't help to compile on non x86 CPUs
2. type make
Ignore warnings.
If you are lucky, it may compile, if not, try using compiled version

II. So you either compiled from source or decided to use binary version, how
to use for first time:

1. prepare flash file, execute following command:
dd if=/dev/zero of=FLASH bs=1k count=16k
2. Download PIXOS image from somewhere, it is tested with 6.35, and 7.21
unzip pix635.bin
mv obj/pix ./
or for 7.21
unzip pix721.bin
mv target/f1/pix ./

edit pemu.ini, it should look like:
-----
serial=0x12345678
image=pix
key=0x00000000,0x00000000,0x00000000,0x00000000
bios1=mybios_d8000
bios2=bios.bin
bios_checksum=1
-----
Don't enter any spaces, or empty lines or something else, as it will not
work!
if you already have image installed in flash, edit the second line to:
image=NONE
Copy Serial No and key from your existing pix, and save file
Activation Key is used only for 6.x version!, for 7.x, key can be entered
with command "activation-key" while system is running
Serial No should be in HEX!!!!!

edit ifup.ini to configure how interfaces are initialized it should look
like this:
------
tap0 10.0.0.1 255.255.255.0
tap1 10.1.0.1 255.255.255.0
tap2 10.2.0.1 255.255.255.0
tap3 10.3.0.1 255.255.255.0
tap4 bridge eth0
------

FINALY, run emulator with:
./pemu -net nic,vlan=1,macaddr=00:aa:00:00:02:01 -net tap,vlan=1,script=ifup -net nic,vlan=2,macaddr=00:aa:00:00:02:02 -net tap,vlan=2,script=ifup -serial stdio -m 128 FLASH
You can use up to 5 interfaces. Make sure that MAC addresses are different
if you want to connect several pix-es.

The latest argument is FLASH image file, -m 128 means 128 MB RAM, which is
required for 7.x
for 6.x -m 32 is enough

Program is terminated with ctrl-c, there are other ways to use serial
console, read qemu manual for more info.

Good luck, and plase don't try to contact me for any kind of support, I
don't want to be contacted, and I really prefer to remain anonymous.
If You really need help, try to post your question to the forum.
