I got that somewhat wrong. What's happening is SATA doesn't get asked that question, even if it's on a SCSI port (I have a USB-A 3.1 gen 2 or whatever to NVMe m.2 M key, and my laptop's internal swappable SATA drive is a Honda connector to dual PCIe m.2 M key, with a single M/B-keyed drive; two shows up as one to the firmware but ZFS can mirror); PCIe or NVMe M key on a SATA port will also not get asked the SMI/EFI question.
You'll wind up with 12.5 MiB Solaris Reserved because it's assumed that SATA is 512b circle-not-square and that's how big one cylinder is. The Wizard could gain +1 UEFI-lore point by asking if the user intends the drive in question to be a boot drive. Otherwise, you can easily wind up with non-illumos-bootable GPT partitioning, or non-UEFI w/o CSM MBR partitioning (a la Ventoy and Rufus btw), instead of PMBR. I'm using format to create and partition my boot drives nonetheless, and so far so good with non-PMBR GPT multiboot partitioning. My forward-interop advice is not to use SATA for boot drives. I'm using lappy's internal bay as a 2TB ZFS mirror (using SK Hynix P31 gold ssd's) as my zone pool. External boot-to-RAM. Internal Compact Express slot has 128GB NVMe drive, and while this is technically a slower interface than SATA, effectively it's higher iops on non-sequential workloads, so it's my L2ARC as I only have 16GB of system RAM. My V110 Gen3 now outperforms my Gen7 on iops, albeit with higher power consumption (mostly due to being 7yo vs. 1yo equipment, I also have a Gen5 but it's out on long-term loan). -Eric ---- On Sat, 29 Jun 2024 14:57:39 -0700 Eric J Bowman via illumos-discuss <[email protected]> wrote --- > format> label > [0] SMI Label > [1] EFI Label > Specify Label type[1]: This dialog, when booted in protected mode (I never should have encountered it on my laptop), indicates CSM firmware present.
