[OpenIndiana-discuss] How to boot oi-dev-151a7-ai-x86.usb inot 64-Bit mode ?

[Sašo Kiselkov]

How did you determine that you are running in 32-bit? What is the output
of "isainfo -kv"? If it prints something like:
# isainfo -kv
64-bit amd64 kernel modules
Then you *are* running 64-bit.

Anyways, should you need to enforce 64-bit for whatever reason, it can
be easily done by instructing the bootloader to pick the 64-bit kernel
(the bootloader does the autoselection magic).

At boot, when the GRUB boot menu shows up:

 1) hit Esc to stop the countdown
 2) highlight the OS entry you'd like to boot, hit 'e' to edit it
 3) scroll down to the `kernel' line and hit 'e' again to edit it.
 4) Remove the $ISADIR portion of the pathname and replace it with
    "amd64". The resulting line should look like something this:
    "kernel$ /platform/i86pc/kernel/amd64/unix ...(cont)..."
 5) Hit Esc to stop editing. Highlight the "module$" line, hit 'e'
    again and edit it in a similar fashion to say something like:
    "module$ /platform/i86pc/amd64/boot_archive"
 6) Hit Esc to exit edit mode and hit 'b' to boot.

If your machine panics, then OI isn't able to use your CPU in 64-bit
mode. You can make these changes permanent once your system boots up by
editing /rpool/boot/grub/menu.lst - replace every occurence of $ISADIR
with "amd64". Be sure to back up your original "menu.lst" file. In case
everything goes wrong, you can always restore it from the Live DVD.
