DS-4900 Fails To Boot (Continuosly Reboots)

Hello 

Found that the switch is continuosly rebooting, following error is seen

I did try to reload the switch from Secondary Partition. ..No-Go as the switch goes back to the same state.

Boot PROM password has not been set.
> printenv
AutoLoad=yes
ENET_MAC=00051E04FFF8
InitTest=MEM()
LoadIdentifiers=Fabric Operating System;Fabric Operating System
OSLoadOptions=quiet;quiet
OSLoader=ATA()0xb9700;ATA()0x3c9bf
OSRootPartition=hda2;hda1
SkipWatchdog=yes

> setenv OSRootPartition=hda1;hda2
> setenv OSLoader=ATA()0x3c9bf;ATA()0xb9700

> printenv

AutoLoad=yes
ENET_MAC=00051E04FFF8
InitTest=MEM()
LoadIdentifiers=Fabric Operating System;Fabric Operating System
OSLoadOptions=quiet;quiet
OSLoader=ATA()0x3c9bf;ATA()0xb9700
OSRootPartition=hda1;hda2
SkipWatchdog=yes

>saveenv
>auto

Noticed the OSLoader to have entry ATA() instead of MEM(). Why is it displaying ATA() instead of MEM()?

OSLoader=ATA()0x3c9bf;ATA()0xb9700

Has the CF gone bad?

Is switch replacement only possible solution or do we have any alternative?

Please advise

Thanks
