Finally got it running on the Lenovo hardware. Lessons learned:
- Don’t even try using UEFI. Turn it off, force the BIOS into legacy mode. Linuxen still prefer yesterday’s hardware.
- Don’t even try installing off of a USB stick. Burn a DVD. Even the SNG7 distro doesn’t really like USB.
Yeah, I know, there are ways around both issues, and that’s a great pursuit for folks who aren’t time constrained to get FreePBX running and operational. If you’re like me, though, learn from my mistakes and save yourself the grief!
