Okay, looking at installboot, BIOCINSTALLBOOT, and sys/dev/softraid.c, I
see that sr_ioctl_installboot() returns an error without explanatory output
if the bootblk or bootloader provided to it are "too big". For boot loader,
that's:
if (bb->bb_bootldr_size > SR_BOOT_LOADER_SIZE * DEV_BSIZE)
and SR_BOOTLOADER_SIZE is 320, so assuming DEV_BSIZE is 512 bytes, that's
160kb. The debugging ofwboot was 250, so too big.
Anyone else have an idea what I could try to see why ofwboot seems not to
be able to load and boot my system from my RAID1 softraid on sparc64?
