 +Don't do it if you don't know what you are doing!
 +
 +Incomplete BETA version of text!
 +**
 +
 +=== Operating system ==
 +  * Set your IP: 10.10.12.2 (alt. 192.168.1.101)
 +  * Mask: 255.0.0.0
 +
 +=== TFTP ===
 +  * Start server listening on: 10.10.12.2 (alt. 192.168.1.101)
 +
 +=== Putty ===
 +  * Telnet to 10.10.12.72 (alt. 192.168.1.1) on port 9000 to get Redboot prompt
 +  * It's better to use ''.bat'' (Because port 10.10.12.72:9000 open only 1 second)
 +  * You can use some usefull script from [[ http://wiki.nslu2-info.de/pmwiki.php/HowTo/TelnetIntoRedBoot | wiki.nslu2-info.de/pmwiki.php/HowTo/TelnetIntoRedBoot ]]   
 +<code>:redboot
 +putty.exe -telnet -P 9000 10.10.12.72
 +goto redboot </code>
 +
 +=== RedBoot===
 +  * Verify config ( last point where you can stop the procedure )
 +<code>fconfig -l</code>
 +
 +  * Clear flash
 +<code>fis init</code>
 +
 +  * Agree with format
 +<code>y</code>
 +
 +  * Download kernel from TFTP server 
 +<code>load -r -b %{FREEMEMLO} openwrt-atheros-vmlinux.lzma</code>
 +
 +  * Create partition for kernel
 +<code>fis create -r 0x80041000 -e 0x80041000 vmlinux.bin.l7</code>
 +
 +  * Download RootFS from TFTP server
 +<code>load -r -b %{FREEMEMLO} openwrt-atheros-root.squashfs</code>
 +
 +  * Check free space
 +<code>fis free</code>
 +
 +  * Create partition for RootFS. Replace 0x2E0000 for number you get as difference between last number of free space and the first number. All in hex.
 +<code>fis create -l 0x2E0000 rootfs</code>
 +
 +  * Verify partition table
 +<code>fis list</code>
 +
 +  * Reboot into OpenWrt
 +<code>reset</code>
 +
 +FIXME
 +
 +===== Verify OpenWrt installation =====
 +  * Telnet to 192.168.1.1 on standard port(23)
 +  * If it does not work try:
 +    1) Telnet to 10.10.12.72 (alt. 192.168.1.1) on port 9000 to get Redboot prompt
 +<code>RedBoot> fis load -l vmlinux.bin.l7
 +RedBoot> go 0x80041000 </code>
 +
 +2) Now you can see Open Wrt promt.
 +<code>root@OpenWrt:/# </code>
 +   
 +3) Thus you have to correct booting procedure. Reboot device
 +<code>Telnet to 10.10.12.72
 +RedBoot> fconfig -l
 +RedBoot> fconfig boot_script_data</code>
 +
 +Enter following:
 +
 +<code>fis load -l vmlinux.bin.l7
 +go 0x80041000
 +
 +</code>
 +
 +Save and reboot.
 +
 +===== Serial on JP1 =====
 +{{:toh:3com:serial.jpg|}}
 +  * brown = gnd
 +  * red, orange = tx and rx (sry, I don't know which is which and now I can't test it)
