Hi,

I have DellR720 server with 16GB of physical Memory. I am testing the
option ROM driver on this server and my  driver is executed successfully.
But while booting Linux from hard disk it failed with the following error
message on screen
"can not allocate memory Failed to allocate scratch mem!".

If i remove my card from server its booted fine.

Here is my question:
1) In UEFI, is there any memory allocation size restriction?(In my driver i
allocated  EfiBootServicesData memory.)
2) is it possible to allocate 4GB of pcie DMA capable memory? In my case it
failed for 64MB.
3) if i want a 4GB of PCIe DMA capable memory how to allocate?

Thanks
Sateesh
