AGP disabled is driving me crazy

[kain]

hi.
I own a Thinkpad R50e 1834-NFG, with specs below:

Original description: P M 705, 256MB RAM, 40GB 4200rpm HDD, 15 XGA(1024x768) TFT LCD, Intel Extreme, 24x24x24x/8x CD-RW/DVD, Intel 802.11b/g wireless(MPCI), Modem(CDC), 10/100 Ethernet(LOM), 6 cell Li-Ion battery, WinXP Home

my problem is that this thinkpad cannot "see" AGP.

as you can see agp is totally disabled, I've tried nearly *everything* from modifying PCI IRQs to open up intel .inf files, from formatting with 2000/xp to respect driver installation order correctly, no way.
Intel's .inf supports agp, as we can see:

Code: Select all

; **    Filename:  852.INF                                                 
; **    Abstract:  Windows* XP INF File for 
; **		   82852/82855 GM/GME/PM/GMV Memory Controller Hub

- under [INTEL_SYS]

Code: Select all

%PCI\VEN_8086&DEV_3581.DeviceDesc%=AGP440_Install,PCI\VEN_8086&DEV_3581

- after

Code: Select all

PCI\VEN_8086&DEV_3581.DeviceDesc="Intel(R) 82852/82855 GM/GME/PM/GMV Processor to AGP Controller - 3581"

but simply this peripheral doesn't show up.

please, can you tell me what's wrong?
video card is a shared memory one, 64mb, and I've 512mb.

many thanks in advance.

ps. I've latest os upgrades, latest bios, latest microcontroller update, latest directx, latest drivers, even tried with those from ibm and intel, no luck..

My integrated graphics desktop(at work) doesn't show agp as well

I've asked both Intel and IBM for this issue.

Intel automated response says that this is a normal behavior since the particularity nature of their architecture.
IBM didn't reply yet.

About what Intel said I'm sure I've seen a screenshot of an user's dxdiag with my exact chipset and agp enabled.

Among other things, someone can clarify why every PCI IRQ is set on 11 per default?

Plus I've read around the AGP440.SYS driver cause many problems and headaches to users, maybe it has been disabled?

Thanks.

the chipset may have been the same, but it could have had a graphics chip by someone else (not integrated)

if it helps...
with some video drivers and 1024 by 768 sisandra shows no AGP at all
changing to 1600 by 1200 (native) you get agp green check on sisandra
bye
