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

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

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,

@kajer why is it so fabulous?

@kajer that's a password an idiot would use on their luggage

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.

kajer

If I do manage to boot a vanilla RHEL, I might be able to pillage some device /asic drivers out of the rpm library I found in the disk I mounted.

kajer

put everything back, but with a video card installed. Managed to stop GRUB in an attempt to get single user mode.

Grub has a MD5crypt password (hashcat -m 500)

yay

I can either change it on disk, or... CRACK IT

kajer

cool, cool... not in the rockyou.txt I have

Time to fire up my CMIYC cluster... my laptop 940MX won't be up to the abuse I have planned.
