Hi Folks,
I have a 16i-MA (A20B-8100-0130 Main board, A20B-3300-0050 CPU, B0F4-19) that I am trying to upgrade from 1MB SRAM to 3MB SRAM (A20B-3900-0020). I'm getting an SRAM parity error when I try to clear SRAM using reset+delete on boot or when I try to restore data to it using the bootloader menu. The bootloader correctly recognizes the SRAM module as a 3MB card. I just wanted to make sure there isn't something at the bootloader level or on the mainboard that would prevent initializing the larger SRAM module. The thing that makes me suspicious is the fact that I get the parity error on restore when it hits the 3rd 512KB file to restore, so it would appear that it can write the first 1MB without issue. I've seen the same behavior on two separate 16i controls I have on the bench, so I suspect I might have gotten a faulty SRAM module but I wanted to check here to see if anyone has other suggestions as to something I may be missing.
I know that this combination of mainboard, CPU, Software, and SRAM works correctly, as its the exact same 16i control build that I have in another machine.
