 All param page: word[0x010000]+word[0x01FFFE]
 @01bde6 Add=0x00971D CalcAdd=0x00971D  ADD OK

Step #3: Reading RSA signatures ..
 Searching for RSA offset #0...missing
 Searching for RSA offset #1...missing

Step #4: Finding CRC table(s) ..
 Searching for CRC table(s)...OK
 CRC table(s) OK

Step #5: Reading Main Data Checksums ..
 Searching for main data CRC pre block...OK
 Searching for main data CRC/csum blocks...OK
 Searching for main data CRC offsets...OK
 Searching for main data checksum offsets...missing
 Main CRCs:
 0) 0x0183C8-0x0183D1                      CalcCRC: F865666E
 1) 0x010002-0x013FFE @8d93a CRC: 7E3A488F CalcCRC: E640C112(r) ** FIXED **

 2) 0x020000-0x0FFFFF
    <fffe0>  Chk: 56503425 CalcChk: 5652254C ** FIXED **

Step #7: Reading Multipoint Checksum Blocks ..
 Searching for multipoint block descriptor #1...missing
 Searching for multipoint block descriptor #2...OK
 1) <1fbde>  0x000000-0x003FFF Chk: 0FA0F5CF Boot: (whitelisted) OK
 2) <1fbee>  0x004000-0x007FFF Chk: 0F4716B3 Boot: (whitelisted) OK

Hmm, WinOLS reported 7 checksum errors, weird.

My file should be good, but why does ME7Sum report 9, and WinOLS only 7?

There are checksum results inside other areas that are also checksummed.
