modify assembly program to solve missed data with new dataflash chip

Hi, I have a circuit that is controlled by an Attiny2313 chip. The program is written in Assembler (source code will be provided). The circuit used to record the data on to this dataflash chip: [login to view URL]?name=AT45DB041B-SC-2.5-ND I have since replace the dataflash chip with this one: [login to view URL]?name=AT45DB161D-SU-2.5-ND The problem is with the new chip pockets of data do not get recorded. (periodically some characters are missing). This did not happen with the old chip. There are therefore some settings that need to be changed and I need someone to make these changes. I have an stk500 programming board and I can program the attiny2313 chip myself. I just need a program to make the changes to the source code. This project MUST be finished by sunday afternoon (EST) Thank you
