This point does not take into account that there could be other PCI devices, not necessarily SAS HBAs, that could get matched by the script.

I ran into this issue when I tried crossflashing on a system with an H310 chipset motherboard. A workaround for this is either modifying the 'ADAPTER_PATTERN' variable or setting the PCI address in the file referenced by the variable 'BACKUP_PCI_ADDRESS_FILE'. I don't think the script itself needs changing, an update to the README.md should be sufficient
