Experiences on Etherboot for IDE Compact flash and FLASHROMS

[Deepak Kotian]

Thanks .I will keep this in mind.

But, I am still too far to see the CF IDE from my LinuxBIOS,
It mostly cannot detect my etherboot  or for that matter even ADLO payload
gives
the same result. It just spins/resets after Jumping to code at xxx .......

Regards
Deepak
