F15B = Fixed BIOS "15b" 965ps3.rar
F15 beta BIOS which fixes F14 BIOS freezing error at boot screen with text "Jmicron PCIE-to-SATAII/IDE" when GSATA is in RAID mode and CDROM attached to IDE slot. This problem is only in F14 BIOS.
Changes from F14:
1. Gigabyte SATA(Jmicron chip) ROM updated to v1.07.14
2. BIOS date 02/26/2010
3. New menu options when pressing Ctrl+F1 in BIOS
It is beta but everything is working perfectly. Can be flashed safely with Gigabyte @BIOS utility or DOS utility from earlier bios.
