Correct. One Philips USB device and One Mushkin Ventura Ultra. Nothing more.

I could have a go, but don't want to brick my device. Happy to write a RW_LEGACY from John Lewis. Or learn how to - bit risky for a newbie? I tried to boot OpenBSD on SAMUS with the USB Philips drive attached, nothing else attached, and got the following output Loading..... probing pc0 com0 mem[639K 1997M 14320M a20=on] disk: hd0+ hd1+* hd2* >> OpenBSD/amd64 BOOT 3.29 boot > machine diskinfo Disk BIOS# Type Cyls Heads Secs Flags Checksum hd0 0x80 label 1023 255 63 0x2 0x0 hd1 Ox81 label 1023 255 63 0x1 0x0 hd2 Ox82 label 1023 255 63 0x0 0x0 Meaning of +, +*, * after hd0+, hd+*, hd2* The '+' character after the "hd0" indicates that the BIOS has told /boot that this disk can be accessed via LBA. When doing a first-time install, you will sometimes see a '*' after a hard disk -- this indicates a disk that does not seem to have a valid OpenBSD disk label on it. OpenBSD developers tell me + means "big disk support". hd0 is my ChromeOS hard disk with OpenBSD installed on it. hd1 and hd2 is the single Philips USB 3.0 disk. It has been zero'd with dd. Seems SeaBIOS is telling OpenBSD, the same drive, can and can't be accessed via LBA, and is and isn't a "big disk support" device. Hope this helps.
