I got Ubuntu to install. I set the BIOS to use AHCI, and added pci=nomsi to the end of the command line, and it worked, albiet somewhat slowly. Point is it’s installed now. The next problem in this seemingly unending road of setbacks is that although the sound works, it’s glitchy. It stutters. It’s not the speakers, I’ve tried both speakers, and headphones. I guess hopefully I can get this sorted out, and if not, we’re a $10 sound card away from getting it working, anyway.
