Description Matt Domsch 2000-11-21 12:00:56 EST

The megaraid driver v1.12 and before cannot handle more than 4GB of RAM.  
v1.12 was supposed to solve this, but is using virtual addresses instead 
of physical addresses for DMA transfers.

PeterJ@ami.com is working to address this issue.

Comment 1 Matt Domsch 2000-12-08 15:14:13 EST

Megaraid driver 1.13beta is included in the IA-64 build 12/07/00, and supports 
64-bit DMA addresses fully.  Closing.
