HDD GURU FORUMS

Hi,

Have a disk with NVRAM corrupted, and i am trying to see a match for a NVRAM.

Have some resources with this:

Selected family......................... : ATMR
Model by ID............................. : IC25N060ATMR04-0
ROM ID.................................. : AD0A
NV-RAM ID............................... : AD4A
RESF version............................ : AD4A

The ROM id and the NVRAM id match the first two letters
ADxx

Also when i see the nvram Report,

Have 10 NVRAM with the CODE AD4A.

NV-RAM report
Loaded.................................. : Yes
Checksum................................ : Ok
mu-code................................. : AD4A
FW Ver Code............................. : 0x4E2E9DD1
Head map................................ : 0 1 2 0
FW boot flag............................ : 0x01

Have 1 NVRAM with the CODE AD0A

NV-RAM report
Loaded.................................. : Yes
Checksum................................ : Ok
mu-code................................. : AD0A
FW Ver Code............................. : 0x4E2E9DD1
Head map................................ : 0 1 2 0
FW boot flag............................ : 0x01

What i do is write the NVRAM in the donnor PCB, to see if the drive work and get the ID.

I am not get any sucess?
Any Ideia, what i am missing here ?

Thanks

sorry, i had check my DB, but don't have anyone fix for you need.

you don't need to match ROM and NVRAM revisions but you need to match ROM CS in ROM and in NVRAM. ROM CS can be found at the very end of the ROM

Hi doomer, i have been searching and i can not match yet the ROM CS with NVRAM.

i see the end off the ROM but no match that in the NVRAM

This example is for a AVVA, that is working.





Thanks
