driver support

Warning: The new driver version 8.23.7 works without the hexediting hack. Just install this version.
Code: now works with 8.23.7 without hack
(II) ATI Proprietary Linux Driver Version Identifier:8.23.7
(II) ATI Proprietary Linux Driver Release Identifier: LGDr8.23g1
(II) ATI Proprietary Linux Driver Build Date: Mar  6 2006 17:25:03
(II) ATI Proprietary Linux Driver Build Information: autobuild-rel-r6-8.23.1-driver-lnx-250560
(WW) fglrx: No matching Device section for instance (BusID PCI:3:0:1) found
(--) Chipset RADEON X850 XT (R481 4B49) found

Thanks ATI :-)


EDIT: Unfortunately this problem still remains with the asus X800xt (device ID: 5D57) and the hex edit hack did and still does not work for this card. If you work for ati or know someone who can make it happen to fix this, please inform them.

Warning: everything below is deprecated since driver version 8.23.7

the Problem

EDIT: The above says "ASUS branded their chips (which are ATI chips of course) with another ChipID than the original ATI-Chipset." I have an x850xt that came directly from ATI and the ChipID is 494b and this is NOT listed in the supported chipset as of driver 8.19. So this in not limited to ASUS cards, this applies to ATI Radeon x850xt AGP cards as well.

Authors Comment: you're totally right :-) sorry about my bad english ...

matching List

a small list follows that it's easier to find the right ID for your card, please continue it, or send me your details (cardname,core chip,original-chipid,used chipid) by mail and i'll add it

commercial Card with official ATI chip Core Chip original ChipID ChipID thats fits to the ATI driver tested with ATI driver version
Connect 3D X850 Pro R481 4b4b (possibly)5D4F ??
mad-maxx Radeon X850 Pro AGP R480 4b4b / 4b6b 5d4f 8.20.8, 8.21.7, 8.22.5
ASUS RADEON X850 XT R480 4b49 / 4b69 5d4d / ?? 8.19.10, 8.20.3, 8.22.5
POWERCOLOR X850 XT PE AGP R480 4b4c / 4b6c 5d4d / ?? 8.20.8

the chipID format is "primary ChipID / secondary ChipID"


find your card Bus-ID

Code: find your card Bus-ID
  • thomas # lspci -v
Note: 03:00.0 is the primary display controller of your card, 03:00.1 the secondary, the values may vary for you

find your chip-id

Code: find your card Bus-ID
  • thomas # lspci -n
Note: 1002:4b49 says you that your chip is from ATI (because of 1002) and the ChipID of this device is 4b49
Tip: you can look up your Chip-IDs here:
Warning: remember both, needed later

lets begin

Code: Install ATI Driver


Warning: use recommended mode, not custom!
Code: after installation run


Warning: (with default settings, means: always press enter)
Note: it won't find your card at the end of the configuration
Note: the start should fail

Code: view the Xorg-log
  • vi /var/log/Xorg.0.log

Note: at this point you should note that your chipid is not in this list :-(
Warning: this sample uses gcc version 3, find out your gcc version with "gcc --version" and cutomise this
Code: useing ht
  • cd /lib/modules/fglrx/build_mod/ #cd to fglrx build-dir
  • cp libfglrx_ip.a.GCC3 libfglrx_ip.a.GCC3_org #make a backup
  • ht libfglrx_ip.a.GCC3
Code: ht action 2
  • cd /usr/X11R6/lib/modules/drivers/
  • cp fglrx_drv.o fglrx_drv.o_org #make a backup
  • ht fglrx_drv.o
Note: the replace step in /usr/X11R6/lib/modules/drivers/fglrx_drv.o is because "ChipID" is not a option anymore (driver version >8.20.) and so the driver didn't recognize your card (btw: big thanks for that comment!)

Code: remove old binaries and install
  • cd /lib/modules/fglrx/build_mod/
  • rm ../fglrx.ko
  • ./
  • cd ..
  • ./
Warning: When you recompile your kernel, you will need to recompile and install fglrx again as shown above!
Note: your motherboard could use sis or something else, check with lspci first!
