Fernando:

My current install of XP-32bit is using an ICH9-2-port and ICH9-4-port
They show up as:

Controller 1: PCI\VEN_8086&DEV_2920 for the 4-port ICH9R
Controller 2: PCI\VEN_8086&DEV_2926 for the 2-port ICH9

The closest that you have from your 64bit-universal driver set which I want to use with XP-64bit are:

[HardwareIds.scsi.iaAHCI_ICH9R]
id = "PCI\VEN_8086&DEV_2922&CC_0106","iaStor"

[HardwareIds.scsi.iaAHCI_ICH9_1]
id = "PCI\VEN_8086&DEV_2923&CC_0106","iaStor"

[HardwareIds.scsi.iaAHCI_ICH9M]
id = "PCI\VEN_8086&DEV_2929&CC_0106","iaStor"

Will any of these three work with my system?

You are correct, it is in IDE mode. The only reason I thought would be advantageous to use the AHCI-drivers was to take advantage of the performance from the "native command queuing"; however, since I only use SSD-drives, there is really no need.

Back in 2011, a colleague and I inserted the SATA-AHCI drivers, SP3, and many other drivers in automated install mode of XP32-bit DVD that we have used many times to install on different custom systems, OEM systems, and laptops with AHCI enabled on some of them and I forgot that the two old systems that I have been using XP-SP3-32-bit since 2012 were left in "IDE" mode during the initial installation.

Yesterday, I tested on an old Lenovo-G530-laptop that had an XP-32-bit installed in AHCI mode which I temporarily removed the drive with the 32-bit installation and inserted another SSD-drive to test the 64-bit version and it would not recognize the drive until I changed it to "IDE" mode, but performance with the SSD is more than adequate and sufficient in IDE mode. I will still insert all drivers and SP2 so that if/when the board's AHCI drivers is supported then it will use them, otherwise, I will use "IDE"; this way the option for "either" will be available just like the customized 32-bit-XP-SP3 version.

hello, I have 0x0000007b bsod due to ahci driver i guess on z590 asus z590 maximus XIII hero.

ID = %PCI\VEN_8086&DEV_43D2&CC_0106.DeviceDesc% = AHCI_inst, PCI\VEN_8086&DEV_43D2&CC_0106

this is not on the modded ahci driver "Universal 32bit Intel RST AHCI+RAID driver v11.2.0.1006 mod+signed by Fernando"

how to add it ?

thank you, i will try it asap

I have tryed to put ahci inf via nlite on a clean xp sp3 32 but still 0x0000007b error.

@vertx

make sure you are integrating for TXT mode and not PNP mode
also use a SATA optical drive not a USB one.

I dont have any Winnt.sif on i386 on this iso.

but i have an other xp iso modded for z490 with it.

I have tryed this, but i have an error concerning the .oem file.

the file txtsetup.oem .... error (257) at the ligne 1747 at d:\xpsp\bas\boot\setup\oemdisk.c

I can’t find it... i will take a look at it asap
