I have used quite a few Neoware thin clients for OpenBSD (and FreeBSD) systems. I boot from an USB floppy or CD on those that support that, or connect a CD-drive to the IDE connector. In all cases I have installed on the internal flash module. Larger modules are available at low cost. Best regards, Mikkel C. Simonsen

It seems like the BIOS looks at the partition table and panics when it sees the OpenBSD partition, which honestly it should not care about. Anti-virus protection run amok perhaps? Either that, or some other type of BIOS bug. -- Shawn K. Quinn skqu...@rushpost.com
