You'll need to check the BIOS for settings related to Intel Rapid Storage (RST) or VMD (Volume Management device) and disable them in order to pass the native NVMe device to OpenBSD. Unfortunately some machines do not provide this option in the BIOS, if that is the case for your machine, you will be unable to install to the internal SSD. -Bryan.

Re: dpb(1) and resource limits?
Here's some practical advice for running dpb with, say, 4 hosts and 16 cores each. > For instance, ssh multiplexing to remote hosts breaks down. dpb opens a ControlMaster ssh connection to the remote hosts and a multiplexed session for each build job. By default, sshd limits this to 10 sessions. For more jobs per host, sshd_config needs to be tweaked, e.g. by adding this stanza at the bottom: # dpb jobs Match User root MaxSessions 16 > I take it that dpb runs into resource limits, dpb itself requires something like 18 + 2*jobs file descriptors. (I don't know the exact formula, the number of hosts probably figures in there. You can try two different numbers, check fstat -p <dpb>, and use your calculator's linear regression feature.) The default file descriptor limit for root is 128, so to run a total of 64 jobs, something like "ulimit -Sn 192 && dpb" is needed. -- Christian "naddy" Weisgerber naddy@mips.inka.de
