Hi
attached file is VBIOS of Apple's version of ATI Radeon HD 2600 - https://www.techpowerup.com/vgabios/209506/209506
it has size 128k because it contains EFI section, none of currently present VBIOSes at techpowerup for Apple ATI Radeon HD 2600 is correct.
this dump was read from SPI ROM of dead board, but used for reflashing consumer's version of ATI Radeon HD 2600
