What is 8 bit checksum

Simple 8bit checksum - Reverse Engineering Stack Exchange

An 8 bit number is a maximum of 255, the highest prime number less than or equal to this is 251 or 11111011 Ans 2. The above is correct for the largest prime storable in a single 8bit storage ...

The carry bit of the sum is wrapped around and added to the result to ensure that the checksum is a 16-bit number. 0x1F81 + 0x1 = 0x1F82 Finally, the one’s compliment of the number is taken to give the checksum.

First, of course, we're computing a 16-bit checksum instead of an eight-bit one, so we're summing words rather than bytes. That difference is obvious. Less obvious is that we're actually computing a ones complement sum.
