Wel that's really odd. OS not found usually means the BIOS can't find
the MBR or the bootloader can't find the partition, the directory of
executables including the OS kernel as described in the boot.ini file
of a Windows OS. I'll have to do some research and find out just what
chips are uploaded code from this 'service' partition just to satisfy
my curiosity.

Acers off the top of my head. Maybe not the current
ones.. But I had to correct an older one that did this.
The owner installed a newer OS, The process reported that
the current partition was not the primary one and asked if
he wish to make the install the primary one etc... etc..
And he did.....................
etc
All was going just fine until it was time to reboot, when
he did, windows could not find the CD rom, any longer.

To fix it, we move the HD to a USB external drive cable I have on
another PC and used the recover CD that restored the HD back to
original. Put it back in the laptop and then install the new OS over
the existing one. That worked out fine..

Take it for what you want, if you have been around long enough,
this isn't a new technique, things like this was done back in the
hay day to configure your HD, the device settings were on the HD
platter.

A lot of these machines had/have simple controllers. Many of them really
don't function much, or not at all. The firmware is uploaded from that
partition or service boot that redirects the boot process, which is a
hard one to fix if you're trying to upgrade.. The devices come alive
when the firmware is uploaded and executed. This is kind of a neat way
of doing things because, you can control the firmware release depending
on the region, regulations etc... For example, lets say we program the
CD rom controller to not allow you to read some security CD's or regions
that don't match yours, Network access depending on where you are, this
way, they don't need different hardware PC's. All they need to do is put
in the correct HD that fits the location of where it's going.

It's also a good way I guess to perform firmware updates by simply
updating the service section and doing a cold boot. That's when the fun
starts if the update didn't go well :)
