You need at least BIOS file 7B58v17.zip. The zip file will contain a file called E7B58IMS.170 - this is the actual file you want to rename to MSI.ROM (as per your motherboard manual) and put on your FAT32 formatted flash drive.
Excerpt from your manual:
"Before updating:
Please download the latest BIOS file that matches your motherboard model from MSI® website and rename the BIOS file to MSI.ROM. And then, save the MSI.ROM file to the root of USB flash drive.
Only the FAT32 format USB flash drive supports updating BIOS by BIOS FLASHBACK+.
- Connect power supply to CPU_PWR1 and ATX_PWR1. (No other components are necessary but power supply.)
- Plug the USB flash drive that contains the MSI.ROM file into the BIOS FLASHBACK+ port on rear I/O panel.
- Press the BIOS FLASHBACK+ button to flash BIOS, and the light of BIOS FLASHBACK+ button starts flashing.
- After the flashing BIOS process is 100% completed, the button light would stop flashing and would be off simultaneously. "
