Just flashed my version 1.0 BIOS to 1.3

Logitech G510 KB still not recognized for BIOS, but found in Win7 64

BEWARE!! system now boots much faster, so much so that I missed hitting del on first boot after flash and system went to load Windows, which then became corrupted--because BIOS flash reset SOME parameters back to default. Hard Drives set back to IDE mode from AHCI which caused corruption. Windows prompted for repair option, which I selected before realizing what had happened, and Windows did a roll back to last good settings--which undid my install of XP virtual Machine and some other programs--PITA!

Prior to BIOS flash I installed an old Zip 250 drive through a USB hub and it appears the ASRock XFast USB (?) keeps disconnecting USB devices in rapid succession. I heard the connect/disconnect tones multiple times in 5 minutes and the drive kept disappearing from Windows Explorer. Is this their USB controller issue, the Version 1.0 BIOS issue, my old USB hub issue, or the Iomega Zip drive? What are the Etron drivers I've seen mentioned here? Do they have anything to do with the USB controller?

I haven't reconnected the hub and Zip drive after the reflash yet to see if it still does the disconnect thing, but I will later tonight and report back on that. Has anyone else had this problem with their Extreme 7?
