Man, how the fuck do i get these disks to boot in ahci mode.

Reset their partition table, rebooted openbsd installer (which saw them), but after install bios hangs so i have to take them out and only after switching back to ata mode theyre recognized and i can boot them. Even tried changing their type with disklabel(1) which didnt complain, but after adding 1 gpt/mbr (tried both) partition same problem.

Any hints? Should i use ata like a boomer cc @pwm @dcc @p
