I tried everything , maybe there is something I don.t know .
I read the manual , I checked all the forum topics , I read this topic more than once but no way .
what does Mikrotik mean by (
The RouterBOARD may be started from a CompactFlash module or a Microdrive hard drive installed in the
CompactFlash slot (J1). At least two partitions must exist on the device, first of which being the ELF image
the board is to be booted from (normally, it is a Linux kernel, appended with the kernparm ELF section that
specifies the root partition name and, optionally, other kernel parameters of your choice).
is the firmware RB800.img not enough ?
I wanna out the firmware on the CF card as you said and boot it from CF . please help .
I know that you want anyone to search before askinf and I really did , so please I need your help
it worked guys , and let me show you the whole process that I did
1- You have to download the latest image from here : http://dd-wrt.com/dd -wrtv2/downloads/others/eko/BrainSlayer-V24-preSP2/2012/07-20-12-r19519/mikrotik-rb800/rb800.img
2- then insert a compact flash card that has 128 MB or more, into your compact flash reader of your PC. ( nowadays it is impossible to find this kind of Compact Flash i mean 128 MB )
3- Now you have to write the IMG file of dd-wrt into the compact flash using a software called physdiskwrite. You can find it here:http://m0n0.ch/wall/downloads/physdiskwrite-0.5.2.zip
4- now you have all what you need , so we are moving to the next step which is to use the x86 instruction
Note : this instruction under windows.
5- now we are going to use normal PC ( windows 7 is preferred)
Put both physdiskwrite and dd-wrt image file in drive c: or whatever your main drive is.
6- Click Start and then Run, type "cmd" in the open box and click open to bring up a command prompt.
7- At command prompt navigate to where physdiskwrite is located. "cd.." will go to next higher directory.
8- type "physdiskwrite -u dd-wrt.image" dd-wrt.image is the actual name of the image file so replace it with rb800.img. The -u tag is used for large drives.
9- Next you will select drive to apply the image to. This will overwrite all contents on drive!! usually your main drive is drive "0" and if you do not have another drive other than the Compact Flash then it should be drive "1".
10- then insert your Compact Flash inside your Mikrotik and prepare yourself to the next step .
11- yon need now a serial cable to be used in changing the default boot option of Mikrotik ( Deafault is NAND )
12- open Hyper Terminal , you might not find it in windows 7 or vista , it is already in XP under Accessories-Communication .
13- The preferred configuration is 115200 bit/s, 8 data bits, 1 stop bit, no parity , flow control : None
14- plug your router and it will show you this message
Press any key within 2 seconds to enter setup
15-then it will show you some options
What do you want to configure?
d - boot delay
k - boot key
s - serial console
o - boot device
f - cpu frequency
r - reset configuration
e - format nand
g - upgrade firmware
i - board info
p - boot protocol
t - do memory testing
x - exit setup
press o and then c to choose booting from Copmact Flash then x to exit the setup mode and then Mikrotik will boor from compact flash .
16- when eht1 is up , it has the default Ip address 192.168.1.1 , now you can use your browser to configure DD-WRT
