Re: Meaning of '+', '*' in disk: hd0+ hd1+* hd2*

2015-11-30 Thread Alexander Salmin
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.

So hd2* means

- cannot be accessed via LBA
- no OpenBSD disklabel

+ means big disk support.

* means no openbsd disklabel. probably not the openbsd disk.

Many thanks. I knew it was man paged / documented somewhere, just
couldn't find it.

Reason for asking?

I have a USB 3.0 device attached to a Chromebook Pixel 2015, and on
booting, SeaBIOS is recognising the same single USB drive twice, as
hd1+* and hd2*.

hd0 is the soldered SSD.

...Looks like two separate issues are occurring - the Philips drive is
being detected as both a high speed device and as a super speed
device.  I need a log with CONFIG_DEBUG_LEVEL=5 to diagnose that...
