I hope that this is the right forum for this question.
I have 5 different mfg. thumb/pen/travel memory drives.
Both a new Memorex Travel drive, and a very old Micro Advantage drive can be booted from, as they are recognized by the ECS Motherboard BIOS as "USB-HD" devices. It's really nice having a 32M drive to boot from somethimes!
The Nexdisk, PNY Attache, and the San Disk Cruiser are not recognized by the BIOS and can not be booted from.
QUESTION : Before I purchase my next pen drive, how can I determine if it is going to be recognized by BIOS? Is there some kind of specification that I should be looking for? Sales people do not have a clue what I am talking about.
