So, unless I need the upper memory support, it may be better for me to |
| 30 |
just not click the flag for 64bit memory support, and move on? |
| 31 |
|
| 32 |
This is on a laptop, and it is not a critical system (i.e. it is not |
| 33 |
going to require that I get those last few dredges of CPU time out of |
| 34 |
the system). The main things it will be used for until I build my next |
| 35 |
system is dataprocessing, and Pencil and Paper gaming. I plan to |
| 36 |
install a couple graphics related apps to mess with and practice with as |
| 37 |
well. :P |
| 38 |

I'm not exactly the average user, but I will be using it for average |
| 40 |
user level work, so it doesn't HAVE to have 64 bit support. :P From |
| 41 |
what I understand, the processor handles 32 bit emulation just fine. |
| 42 |
(It was running Windows XP fine until a runin with the emphamous Gentoo |
| 43 |
GTK installer.) |
| 44 |
|
| 45 |
:P I'm not blaming the software though. The Walkthrough, and the |
| 46 |
readme both warn that it is experimental. ^^;; Then there is the fact |
| 47 |
that I had just butted a 700MB CD, that loaded a compressed file system |
| 48 |
into 512MB of ram, and told it to load a GUI, and a GUI driven install |
| 49 |
system. *shrugs* Live and learn, and kick yourself when you do |
| 50 |
something stupid. :P |
