Trouble with GreenProg and milk...

[vmehta211]

I am trying to program a SST49LF020 with a CheapLPC programmer. I am using GreenProg and have also tried milk. Both programmers give the following type of error: "Incorrect manufacter ID Returned: FB, Should be BF"

I have no idea what this means. All I want to do is flash my SST49LF020 with a bios. If anyone knows what my problem is or what is another test I can try to make sure my programmer is working correctly, please let me know.
