What ever came of this?thanks for the reply.
BIOS system settings:
BIOS version: E7B27IMS.170
MB: H310M PRO-VHL (MS-7B27)
Product Name: MS-7B27 1.0
Motherboard installed in PC is B360M Gaming Plus
above PCI-EI slot: B360M GAMING PLUS
BELOW PCI-EI slot: MS-7B19 VER1.1
Definitely the wrong BIOS installed. Bought new motherboard from supplier, not part of OEM system or pre-build. www.evetech.co.za.
Physical appearance is as it should be, correct box etc.
Some features not working, eg. only 4 sata ports in bios working, mobo has 6. LAN port not working,
It would see the drive but wouldn't list any bios file to select for flashing.
