Binary package hint: grub2
From: USB stick setup as bootable from GUI tool in Jaunty with Karmic AMD64 alpha 5 alternate install ISO
To: Empty disk (had to remove old partitions to get rid of autodetected LVM vg, etc.)
On rebooting, BIOS hands off to grub and grub boots default without any opportunity to choose to boot something other than the default. Due to other problems (more reports to come), I am assuming that this is grub2 (it's supposedly the default for new installs). It's possible that whatever grub2's equivalent of menu.lst is simply isn't setup to allow any choices. |
Binary package hint: grub2
Grub2 has switched away from a minimum 1 second delay to hit enter, in preference to simply holding down shift during the boot sequence. However, this behaviour doesn't work on all machines.
Further, many users will only learn this after their machine fails to boot normally, leaving them unable to boot at all without outside assistance. |

Binary package hint: grub2
Ubuntu added a patch on top of mainline GRUB and Debian such that holding down the Shift modifier key during boot will cause it to display
the hidden boot menu.
In the original IBM PC/AT design the modifier keys (Shifts, Ctrls, Alts) are handled separately to all other keys. Instead of reporting state transitions there is an I/O port register that is read by the software where each bit position represents the current state of the associated
modifier key.
The functionality to read this I/O port register works correctly for BIOS systems or UEFI systems starting in Legacy/CSM mode.
On UEFI systems this does not work. The reasons are:
1. At the time this Ubuntu-specific functionality was added to Ubuntu the UEFI specification, and UEFI implementations by manufacturers, did not provide a way to detect the state of the modifier keys.
2. UEFI only provides the same mechanism as for all other keys: detect a transition of state (key_down or key_up).
3. When GRUB timeout is set to 0 (zero) there is no way to detect a key press transition.
It appears that UEFI specification version 2.4 may now support the required reading of modifier key state so I shall be investigating whether we can now add support for UEFI systems that implement the v2.4 specification. |
