CSM isn't compatible with DDR-6. UEFI's won't have CSM, soon. My only multi-session optical media that works with UEFI-CSM is BD-RE which was never bootable to begin with. If I had some other multi-session media format, I don't think it would work without CSM any better than distro.iso's which forgot -no-emul. Whole lotta Rock Ridge options won't be valid moving forward, due to incompatibility at the "alignment" level, like offsetting an overlapping partition containing the real distro.iso -- at best, gets you 16-bit real mode that only the Intel 8088 MINIX Experience doesn't care about -- due to NVRAM; it just loses access to system RAM w/o CSM.
UEFI says Rock Ridge. UEFI* lists some things which translate to, "won't work without CSM" while hewing to Joliet without saying so, but comes as no surprise because Joliet's Windows. I don't think Joliet's multi-session compatible, but I also note, UEFI allows booting a standard .iso in a partition with an MBR -- not that said MBR is required to point to anything actually existing, which defaults to pointing to -- Windows. -Eric ---- On Mon, 10 Jun 2024 10:54:02 -0700 Eric J Bowman via illumos-discuss <[email protected]> wrote --- Indeed.

In xa1 mode (muiltisession CD), sectors are 2056 bytes, so that won't fit into 65536 ... ------------------------------------------ illumos: illumos-discuss Permalink: https://illumos.topicbox.com/groups/discuss/Te6d81d754118b912-M697400f9adc1c407de89645d Delivery options: https://illumos.topicbox.com/groups/discuss/subscription
