Dear gentoo users.
After years of FreeBSDing, i've discovered your magnificent OS,
Many thanks to everybody that makes it possible
I assembled the following system
ASUS A8N-SLI (Nforce-4)
AMD64 3700+
2GB (2x1 GB Double sided DDR-PC3200)
WD 74GB SATA Raptor
ABIT Radeon X700 256 MB
Kernel 2.6.11-gentoo-r7 (x86-64)
Xorg 6.8.2
Ati 64 bit drivers v. 8.12.10
The gentoo 2005.0 install was relatively easy with the excellent
documentation,I'm running a stage3 -> stage1 64 bit build as advised in
the mailing lists with great sucess, my only problem was getting the ati
propietary drivers to run.
Starting X with the fglrxconfig generated xorg.conf would freeze the
system.Only after many reboots (and having installed Win XP on a
secondary disk to check for a defective card) i discovered that
Option "mtrr" "on"
Did the trick.
A problem might still remain
The following appears in dmesg
mtrr: base(0xc0000000) is not aligned on a size(0x7ff0000) boundary
/proc/mtrr reads after booting
reg00: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1
Only after some use, it gets "populated" as follows
bash-2.05b$ cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1
reg01: base=0xcfff0000 (3327MB), size= 64KB: write-combining, count=1
reg02: base=0xc0950000 (3081MB), size= 16KB: write-combining, count=1
reg03: base=0xc0940000 (3081MB), size= 64KB: write-combining, count=1
reg04: base=0xc0900000 (3081MB), size= 256KB: write-combining, count=1
reg05: base=0xc0800000 (3080MB), size= 1MB: write-combining, count=1
reg06: base=0xc0000000 (3072MB), size= 8MB: write-combining, count=1
I hope this info might help someone.
Regards,
Roberto
