Great, now I am looking at hardware firewalls on ebay for a side project to do

kajer

I'm in... First order of business would be to image the drive I guess

kajer

And this is why we keep old shit laying around

kajer

Moved the motherboard onboard VGA to disable, and viola

kajer

oh snap - we can make this a dual xeon board

So I set the cmos date to 2024, and then got the no-vga beep code...

After finding that the CMOS reset jumper was never installed, I got the CMOS back to default

Booted an opnsense iso .. nope

kajer

oh fuck, 32bit xeon.... wow

kajer

also, 1GB of DDR2 400

let me check my stash

kajer

Okay, now we are getting something

Found a stash of 2gb pc2 reg ecc

Got the date up to 2024

The old CMOS battery was cooked

kajer

omg, i can finally take an image

turns out, when using bad ssds that still test "okay" from a NAS... are actually bad.

who knew

kajer

A minor annoyance, all screws are stainless. My magnetic driver has no effect. Nice build quality I guess.

I just want to boot an OS so I can see WTF the dataplane board shows up as in LSPCI

kajer

I seem to be ignoring the obvious... replacing the motherboard with something not 3000 years old.

kajer

I got an X11 generation motherboard installed with some minor chassis modification. With the ASIC card installed, the server wont post. no beeps, no vga, no anything.

Going to stop fucking around with the hardware, and start to disassemble the disk image i took,

I was unsuccessful in getting a different OS on the existing motherboard.

PXEboot results in continuous beeping just after trying to get the pxelinux.0 file

Booting FreeBSD11 results in a partial load of the kernel until something beeps and the boot hangs.

Booting various i386 linux is the same, something causes a short beep and the boot process hangs.

I swapped the X6 motherboard with a X11, but with the ASIC installed, the MB won't post.

kajer

I dug in to the OS a little bit last night after doing hardware stuff. The OS is based on RHEL but can't quite tell which version.

I am thinking I clone the HDD back to another disk, but inject a root password in to the shadow file so I can login to the underlying OS before PanOS takes over getty.

kajer

@ryanc My guess is: It's a custom bios that supports some sort of additional PCIe expander.

Given the issue that the ASIC card won't let me POST on another newer motherboard, but that is just a guess.
