    In many situations, we need to read and write ROM when HDD can’t be identified. So MRT Seagate module provides BOOT model tools, the tools can read or write ROM chip of circuit board when HDD is not ready. It is mainly used for ROM data backup, remove or revise.
   When HDD is not ready and you need to read and write ROM, firstly put HDD circuit board into Boot Code module, it needs short circuit. We prepare a file; explain how to short circuit in Boot Code module. Download address of the file: https://vip.mrtlab.com/showdown.asp?id=11

    Now we enter Seagate module, short circuit HDD into Boot Code module, then we can continue the follow work. Now we link the HDD circuit board to MRT COM port serial, first short circuit and then power on. We can see HDD shows Boot Code COM port. If fail, try several times. Pay attention to that there are many ways to enter Boot Code module. For example, when Seagate 12 HDD power on, press U key in COM port can enter Boot Code module, but at that time it lacks suitable situation to enter Boot Code module and can’t read and write ROM. That is to say, if you want to read and write ROM, you must use the way of short circuit to enter Boot Code module, other ways are invalid.

    In order to make the speed of read and write ROM faster, we firstly set up a faster communication baud rate, it can greatly improve the speed. Select “COM port - Synchronous set the baud rate”, introduce to select 460800 baud rate, select “Boot Code module”, and confirm. After set up, we press enter several times in COM port to see whether it has reaction or not. If it has, the new baud rate has been set up successfully. If it hasn’t, set up fail, HDD may lose synchronization with MRT COM port and you must return MRT to former baud rate.
    Then we need to enter “Serial binary BOOT model”. Follow is processes:
1. Checked “Serial binary BOOT model”
2. Checked “Serial binary mode”
At present, you enter “Serial binary BOOT model” normally, the orders can’t be reversed.
Quit “Serial binary BOOT model”. Follow is processes:
1. Get rid of checked “Serial binary mode”
2. Get rid of checked “Serial binary BOOT model”
The orders can’t be reversed; too, otherwise the program may hang up for a while.

After enter “Serial binary BOOT model”, we can open “BOOT model tools”. The usage is simple, if you want to read ROM, press read Flash ROM key, then waiting, the whole ROM data could be read to the follow sixteen hex translators. If you want to preserve the data of sixteen hex translators to file, just press “preserve to file”.

The processes of write ROM are similar to it. First short circuit enters to Boot Code module, then set up baud rate, set up MRT enter to “Serial binary BOOT model”, open BOOT model tools. Press “open file” key, loading ROM data which need to be written into the follow sixteen hex translators, press Write Flash ROM key, then it begins write ROM. Wait for a period of time, after finished write ROM, cut power directly. Quit “Serial binary BOOT model”, power on, you will find the new ROM has been taken effect.

Above is the usage of ROM read and write tools.
