Watchguard XTM 5 Series

@stephenw10 I was able to flash the image to CF and then install from the same CF.

I also flashed the new bios, so let me know if any settings I should change there.

SSD and HDD will still not boot all the way.

stephenw10

With the unlocked BIOS you can boot from USB which might enable you to try some other things. At least you could boot USB and install to CF giving you the full card size.

@stephenw10 Tried to boot from USB but am getting a message about needing to insert proper media.
I have a usb drive with pfSense-CE-memstick-serial-2.4.5-RELEASE-p1-amd64.img

stephenw10

You will probably need to enable it in the BIOS. It's been so long since I did that I've forgotten what the defaults are. It can be made to boot USB. Mine does.

@stephenw10 Here are all my bios screenshots:

stephenw10

I have Mass storage emulation type set to 'auto' otherwise it's the same.

Are you sure the image is on the USB drive correctly? I recommend writing it with Etcher.

@stephenw10 Not sure what happened, attached an SSD I had tried before and now it works

Has anyone upgraded the fans?

stephenw10

You can replace them with something from Noctua for example. There are some references in this thread. I never bothered once I could set the minimum fan speed with WGXepc, those Noctua fans are expensive!

@dog2bert Noiseblocker BlackSilent Fan XM-2-40mm does the job for me, cheap and silent, even at full speed. The watchguard is in my living room.

@stephenw10 What value should I use for the fan speed?
Can you set it in the BIOS now that I have it unlocked?

Is 10 safe?

Looks like the -f command doesn't work on the 5 series only -f2

/conf/WGXepc64 -f2 10

stephenw10

I have the system fan set to 50. The CPU fan is connected to the other controller and WGXepc can't set that (yet). You can set it manually though.

I am safe to use this image to update my BIOS from https://sites.google.com/site/pfsensefirebox/home/xtm5_83.rom

stephenw10

They should all be compatible AFAIK, I've yet to see one that was not. That's just the date from the gen2 models, there are a few posts here confirming it works. For example:

Of course flashing the BIOS is always inherently risky. You could lose power part way though etc...

And you're running the wrong OS...

@stephenw10
Thanks Steve... BIOS flash was successfully...
Still playing around with different firewalls before going production... if that makes sense

The original Watchguard CF card OS boot is able to start Recovery Mode (SysB) or Safe Mode (SysA Safe) from LCD Keys
I think is something embedded in MBR or in GRUB stage...

I had a crazy idea... how shall be hard making a multiboot like that to choice via LCD keys which disk / partition will have to start ?

Obviously i think who should be the right one for the answer...
Stephen i'm very cold about ASM or C coding...
I can only give an original Watchguard CF image and no more right now.

stephenw10

I believe that code is in BIOS and passed to GRUB. You will still see it try to boot recovery even without a CF card present.

Steve

DaveAngel

@stephenw10 sorry for the delay... i tried without the CF Card and nothing happens during the startup phase on the LCD pressing UP or DOWN button of the case keypad... only the WG BIOS V 1.2 stay.
But you could be in right and some code could be embedded in bios too to storage a flag value somewhere...

I'm affascinating by bios and i wish spend time investigating.. please may you give me some hints about software you used to modding the XTM5's AMI Bios ?
I tried to search on the web but i found only recent software that don't recognize this 1024k ROM.

@DaveAngel

[1] Install the flashrom tool

pkg
pkg install flashrom
rehash

[2] Download the new flash image

cd /tmp
fetch https://sites.google.com/site/pfsensefirebox/home/xtm5_83.rom
md5sum xtm5_83.rom

The MD5 has should be: e75bc93ca2db547a3facb8d611f0d441

[3] Reprogram the flash

Read and save the original/current flash image

flashrom -r rom.original –programmer internal

Write the new image

flashrom -w xtm5_83.rom –programmer internal

Verify the write was successful

flashrom -v xtm5_83.rom –programmer internal

Pull the CMOS battery & mains power, wait a few minutes, reboot & voilà.
If everything's OK you can delete the new image file with:

rm /tmp/xtm5_83.rom

stephenw10

For actually editing the image there are a number of tools that can open and modify the older pre-uefi AMI BIOSes. Including AMIs own proprietary tool amibcp. You'll have to go searching for that if you want to use it.
Bare in mind it's very easy to make an image that doesn't POST and then you need to reflash the chip directly. I did it several times!
