They had a special 1-2 meg partition on the hard drive that the bios looked for and not finding, would hang the system. "OS NOT FOUND" I found out the hard way, loading SCO Unix on one, going through the entire ordeal of loading the operating system (and mistaking wiping the service partition, then rebooting and finding I had to (a) replace the service partition and reload the service software and (b) start from scratch again with SCO Unix install.

Caused all sorts of mayhem. If I recall the trick was to wipe the MBR and sys the drive from a floppy boot disk. -- Best Regards: Baron.

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.

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 :) |
