I had another go at this today
I used the latest snapshot, 6 September: sha256sum install68.iso aa7b5270506dcccd80045dae22fb8a6aeb4c892d71f74c6e27175d30295f9b17 I removed the LSI HBA and I put a blank SSD into a Sharkoon USB 3 dock. The installer was able to install into the docked SSD When the machine rebooted, the Talos II bootloader, petitboot, did not display OpenBSD in the list of boot options I exited the menu to check the petitboot shell and using fdisk, I can see that the petitboot kernel has found the USB dock. It seems that the petitboot menu system isn't recognizing the OpenBSD partition. Can anybody make any suggestion how to troubleshoot or how to select the partition and make it boot? # fdisk /dev/sda The number of cylinders for this disk is set to 21889. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): p Disk /dev/sda: 168 GB, 180045766656 bytes, 351651888 sectors 21889 cylinders, 255 heads, 63 sectors/track Units: sectors of 1 * 512 = 512 bytes Device Boot StartCHS EndCHS StartLBA EndLBA Sectors Size Id Type /dev/sda4 * 1,5,5 1023,254,63 16384 351646784 351630401 167G a6 OpenBSD
