Dumped BIOS only FF may not be proper dump, try again with another software version, I doubt the chip is blank (All FF) even if corrupted. That is common issue with programmer when bad connection, connected improperly, using incorrect version, or incorrect chip ID used etc. Here is several versions of the software for CH341A programmer -

Or is this removable BIOS? If yes, make sure you are putting chip into correct slot in the programmer and that pin one lines up with correct place in the programmer. Of course, if you have ever pressed "write" or "erase" with the chip connected, then it could be blank, if you have not, then it should have data on it
As I mentioned, you cannot write that .27 BIOS to the board, it's not complete BIOS. What is CPU model on this system?
Hopefully you have not erased or written to the chip, so we can get good dump from it. I cannot find one online, so that is your only hope I think, if it's corrupted I can fix, but if it's empty we cannot. I bet try other software version and you will get good dump. What is the BIOS Chip ID?
