Blue screen in iastor.sys (T60p, Windows XP)

T60p, Windows XP Professional, latest versions of everything as far as I know (except for next-to-latest version of video driver because the latest version causes a blue screen on resumption from standby).

I have a music software application (E-MU Proteus X2) that works just fine on my Dell desktop machine, but when I try to run it on the T60p, it reliably crashes with a blue screen:

*** STOP: 0x0000008E (0xC000005, 0xB9E36B24, 0xAAF63BA0, 0x00000000)

*** iastor.sys – Address B9E36B24 base at B9E2F000, DateStamp 45d0d237


Any suggestions?

The software requires a 7200 rpm disk drive for streaming - so I think it must use a direct-read/write access method for the HDD. IASTOR.SYS is the SATA driver for your Tpad. Blue screen means that something in the kernel protected mode is getting trashed when you start the program - in this case the HDD driver. Solutions would include either a software patch/update for E-MU or a driver update for the Intel chipset that contains the HDD driver. I would check Creative first, and leave a bug report also. They probably never tested the software driver with Intel Mobility chips.

Check in the bios to see if your sata controller is set to ACHI or compatibility. I had my T60 set to ACHI and my T60 would crash all the time. I set it to compatibility and haven't had a problem since. I also don't know any speed difference.

Good luck,

That's interesting, because this document sure seems to urge people to use ACHI:

http://www-307.ibm.com/pc/support/site. ... MIGR-66020

In any event, I am nervous about turning it off, because then whenever there is some other problem, I'm going to have to turn it on again to be sure that ACHI is not the problem.

Am I mssing something here?

Also, note this:

http://www.intel.com/support/chipsets/i ... 015988.htm

WARNING: Switching SATA modes in the BIOS after installing the operating system is not recommended or supported when a SATA drive is the boot drive. Switching modes may cause an immediate blue screen with an 0x0000007b error code, followed by a reboot.

I go by personal experience not what intel or IBM tell me to do with the SATA setting. I have used both modes and I have problems with BSOD when I have it set to ACHI. I rebuild my notebook often from scratch not the IBM restore method. If you are nervous about changing the setting and getting a BSOD right away then make a restore point and change the setting back and revert to the restore. If I recall right, I think windows may find new hardware when you change modes but it takes care of things for you.

This is the solution: :D

[SourceDisksFiles]
iastor.sys= 1,,,,,,4_,4,1,,,1,4

[HardwareIdsDatabase]
PCI\VEN_8086&DEV_27C5&CC_0106 = "iaStor"
PCI\VEN_8086&DEV_27C3&CC_0104 = "iaStor"
PCI\VEN_8086&DEV_27C1&CC_0106 = "iaStor"
PCI\VEN_8086&DEV_2652&CC_0104 = "iaStor"
PCI\VEN_8086&DEV_2652&CC_0106 = "iaStor"
PCI\VEN_8086&DEV_2653&CC_0106 = "iaStor"
PCI\VEN_8086&DEV_24DF&CC_0104 = "iaStor"
PCI\VEN_8086&DEV_25B0&CC_0104 = "iaStor"
PCI\VEN_8086&DEV_2821&CC_0106 = "iaStor"
PCI\VEN_8086&DEV_2822&CC_0104 = "iaStor"
PCI\VEN_8086&DEV_2682&CC_0104 = "iaStor"
PCI\VEN_8086&DEV_2682&CC_0106 = "iaStor"
PCI\VEN_8086&DEV_282A&CC_0104 = "iaStor"
PCI\VEN_8086&DEV_2829&CC_0106 = "iaStor"
PCI\VEN_8086&DEV_2681&CC_0106 = "iaStor"
PCI\VEN_8086&DEV_27C6&CC_0104 = "iaStor"

[SCSI.Load]
iaStor = iaStor.sys,4

[SCSI]
iaStor = "Intel(R) 82801 SATA RAID/AHCI Controller (ICH5,6,7,8,9)"

BIG thanks to my friend Baudouin :wink:
