well there right you would need board that could boot via the pci-e slot. So if there is no option in the bios of the board then it will not support a Pci-e SSD as a boot drive.
It will only support the drive through windows once the drivers for the card are installed.
Your solution would be to look for a board that supports booting from the Pci-e slot, there is no other way around your problem.
thanks for the reply!
no driver is required for windows to see the drive - as soon as i installed it, it showed up in disk manager. so it's just a boot issue.
the pci-e ssd appears as a drive connected to a marvel sata controller. does this mean that this system board (and presumably most others with AMI BIOS???) can't boot from a device connected to a SATA controller in an expansion slot? that seems ridiculous!!
