Don't know how similar this might be to the 505, hopefully there's at
least some parallels...
On my HP Omnibook, this beeping is simply an indicator that the key was
noted by the BIOS.
If the BIOS doesn't consider the partition "right", it simply won't
perform the suspend-to-disk, although on the OB at least, with some
(later) BIOS versions it will suspend-to-RAM instead at this point (the
original BIOS simply didn't do anything other than beep if the partition
Simply creating a partition of the correct size (RAM + video RAM,
rounded up to whole cylinders, IIRC) & type (0x160 for me) in the same
location the recovery CD would put it in (slice 1) doesn't seem to work,
and even a cobbled-up 'phformat' (hacked to compile on -STABLE) doesn't
seem to convince it to work. I suspect there's some other voodoo
In fact, the only method I've found that works for me is to initialize
the disk (including a suspend partition of the appropriate size) from
the recovery CD, drop out of the install when it starts to install Doze,
boot the installer and delete the 'Doze partition from sysinstall and go
on to install FreeBSD from there.
Both my old 5700 and my present 6000 were identical in this respect.
Then suspend-to-disk works perfectly modulo certain devices on the 6000
- sound and trackpoint, IIRC - never getting re-attached after a
resume-from-disk; they behave like they're no longer there...
However, this is still much better than needing to fsck after the
battery runs down - possibly whilst suspended-to-RAM in your backpack. A
BIOS-controlled auto-suspend to disk and power-off on battery exhaustion
followed by a reboot when back on A/C works pretty well.
