At long last I have managed to do this BIOS update. The BIOS updates suppled
for the machine can only be applied in windows 7 or 8. Have tried XP and
although the logfile says that XP is supported it BSOD'd on me. I tried FREEDOS
but this was time wasting because:-
a) A floppy image is too small
b) USB has to be NTFS formatted not FAT32, screen just flickers
c) After burning the 10MB image to CD and booting from that you find that
the BIOS installer will not run under DOS despite FREEDOS being an alternative
to windows and Ubuntu. A bit remiss of HP I think.
I had to download a win7 installation dvd ISO, burn it to DVD, boot from
this, select repair, then run a command prompt. I had the update file
(sp65847.exe) on a USB memory stick which became drive C:.
The BIOS flashed ok but ended very abruptly in a reboot and wouldn't
reboot initially as had tried booting from the flash drive which wasn't
NTFS. After powering off/ on again it then implemented some other
changes before rebooting as normal.
No change to the touch pad though, still unuseable. Output from above
two commands as follows:-
paul@tancove-lt2:~$ sudo dmidecode -s bios-version && sudo dmidecode -s
bios-release-date
[sudo] password for paul:

Only issue on reboot was a cmos checksum failure which the machine did a
reset to, and advised checking BIOS params. Only thing I noticed was
that the virtual machine facility was switched off in the BIOS which I
turned on again.
** Changed in: linux (Ubuntu)
Status: Incomplete => Confirmed
