PM25LV010 GPU bios read/write

I am attempting to read a bios from a Gpu and then write a new one.
I am using a FlashcatUSB with a 8 pin pomona soic clip.
What settings do I need to use to get a reliable read?
I can read the first part of the bios in the HEX area of the SPI flash tab but that is when selecting Atmel AT25256B in the (Settings ->SPI EEPROM mode -> AT25256B)
My chip is the PM25LV010 and the bios filesize should be 128 KB.
Thanks.
 
You should never use SPI EEPROM mode for anything EXCEPT those specific devices (i.e you are ACTUALLY trying to read/write to a AT25256B).

You should let the software detect automatically or contact the manufacturer for any unknown devices. You should expect to hear a response within 24 hours.
 
Ok, so they sent me an updated Beta Exe that adds support for the mentioned eeprom.
I can do a full dump and erase but when I flash I get a couple of flash verification errors at 0x0 and 0x1000 .
I dump the chip again and compare in HEX Workshop and there is missing data in the dump.
Thanks.
