2148a and 2148af flash

we have a new system up and working. we have a reflash routine that bootsraps a complete new program load, using the user programming mode using 128 bytes at a time, and it works fine on the EVB( which has a 2148AF chip)
However we have 2148F chips in circuit.I am confused about what I actually have??- Is the 2148F chip the std or A-mask version, does it use 32 or 128 byte programming and does it need the pin 9 cap or vcc conection- currently on 5volts we have the pin 9 cap & everything works 100% , inc erasing, except for user programming.??
