I’m oso2k on bttr. I don’t have bocke’s issue with booting my Book8088 v2 with FreeDOS. I don’t know if they are having hardware issues. I booted FD1.3 Floppy Edition on a Dell 316SX (386 16MHz) and have formatted a 256MB CF and a 512MB CF. Both cards boot on my Dell 316SX and Book8088. I shared images with the bttr folks.
There have been various reports of various issues with some of the chips (CPU, ROM, RAM, CGA, VGA, DAC, OPL, etc). Many of the chips are scavenged parts from other machines. So it makes sense some of them could be duds. It would be the first I’ve seen that the IDE controller is faulty but I’ve also not researched issues extensively. I’ve been fortunate to have a Book8088 v2 that seems to be unaffected by bad chips for the things I’ve played with.
