Got an interesting one here for you folks…
I have an ECS K7S5A motherboard with an AMD CPU that won’t boot from a USB Hard Drive.
1) The motherboard does support boot from USB hard drive, and I’m using the latest BIOS.
2) The Hard Drive uses an EXTERNAL power supply, so it’s not a matter of having sufficient power.
I installed both XP and Linux to the drive (a Western Digital 20 GB in an external enclosure), and it boots on another PC just fine, though with a different motherboard in it.
Any ideas?
