How to gain access to the installed partition of XG Firewall to modify boot so only text is seen via console

Hi All,

I recently managed to install SW-17.5.9_MR-9-577 on a Check Point 2200 device, but once XG has installed and the device is rebooted all the text seen on the console is junk.

I tried to see the boot partition in Linux and Windows but the entire disk is show to have nothing on it but yet it boots.

How can I gain access to the boot folder/partition so I can modify it to send all text to the serial port?

Thanks,

Hi All,

I tried the advanced shell and I can't find the boot folder or the grub.cfg anywhere on the disk.

Put the speed on the serial connect on my putty session to 38400 but still no luck.

Hi Ghost Coder

What you are trying to do is not supported. Also when you update firmware, this will be overwritten.

As previous post has stated, it sounds like your baud rate is not set correctly. It could be in BIOS where its set too low for the XG code. The XG code is set to 38400. If the hardware does not have that set as that speed, then you will have issues.

Thanks!
