Hi, |

You don't need to go to bed :) Just setup your kernel to use High-Memory: |
| 4 |
cd /usr/src/linux; make menuconfig; then item: |
| 5 |
Processor type and features -> High Memory Support -> 4GB |
| 6 |
And it's done, but keep in mind that userspace processes will still be limited |
| 7 |
to 3GB of memory use (AFAIK) (if someone would like to correct me, he is welcome). |
| 8 |
|
| 9 |
If you want your processes to use more than 3GB of memory, then yes, boot up |
| 10 |
with a 64bit OS (again correct me if i'm wrong) ;) |

HTH. |
