    I am not all that familiar with Intel hex, but, the standard Intel Hex
had only a 16 bit address, thus it could only work up to 64K bytes (plenty
back in the 8080 days).  The extended format increased the address range.

    S1,S2,and S3 denotes the size of the address, 16,24 and 32 if memory
serves me right..

    A binary file is just that, binary.  Each byte in the file coresponds to
a byte in the eprom.  ASCII is similar, but is more like a hex dump of a
binary file.  Each 2 characters make up a hex number that lives in one byte.

    YOu might want to post the file.  I could look at it and tell you what
it is.
