External drive question
I have a Seagate Expansion Portable Drive external drive amd have a problem
with it. If it is plugged in when the system (Emachine T2984)is booted XP goes to the drive and won't boot. I have to unplug the drive before booting. I'm sure that there is a setting somewhere so that I can leave it plugged in. Daily plugging and unplugging is hard on the connectors. TIA -- I love a good meal! That's why I don't cook. |

TIA It sounds as if you need to change the boot order in the computer's BIOS. |

TIA It sounds as if you need to change the boot order in the computer's BIOS. Emachine T2984 is year 2005. The BIOS might not have the module for USB boot, as USB booting seemed to start with machines with USB2 ports, rather than USB1.1. I have a P4 with SDRAM and USB1.1 ports (ICH2), and it doesn't have USB boot. A later P4, did have USB2 boot. I couldn't find any really good datadumps on that model of machine. For example, there's no mention of what model of Bestec power supply that uses. (There is one evil Bestec, that when it fails, it overvolts on +5V and damages a lot of nice hardware in the machine.) That doesn't imply this is the root cause of anything, but if the word "Emachines" comes up, I like to encourage people to look into that issue "what Bestec is the broken one". At a minimum, an Emachines owner should have backups of their hard drive, with the backup image on external storage, for when that PSU blows. The supply has a model number printed on the label (visible when the computer side panel is open). Perhaps if a self-powered (wall adapter) hub is used for the drive, that will provide more isolation and allow boot to finish. Emachine | USB1.1 | Powered Hub -- wall adapter | | | | | | External drive There is one application note from the USB Hub chip companies, that shows a relay being used to disconnect "bus" power when the wall adapter is used. But nobody at retail makes hubs that way. As a result of this lazy design attitude (not doing it right), sometimes a hub doesn't provide the desired degree of power isolation. (To prevent an external load from influencing machine operation.) At least one poster here, had a "backfeed" problem, where an external USB hub actually pumped current backwards into the USB port. This can lead to flaky behaviors. Paul |
