Trying to dual boot a Win 7 machine with XP 2nd O/S

[Rick12]

I was advised a week ago to slipstream XP's service pack 3 into an XP installation disk. I did so and I still get a failure that indicates the same issue about the hard drive:

 

Stop: 0x0000007B (0Xf78da63c, 0XC000034, 0x00000000, 0x0000000) [Note: that C in the second error field may be an artifact of my lousy handwriting, maybe it was a zero]

 

I used Seven forum's tutorial to do the slipstream of the service pack, it seemed to work. I still suspect the SATA driver is the problem. However, the tutorial which used adding SATA drivers as the example indicates an .INF file is necessary. I went to the Intel website and downloaded "STOR_allOS_8[1].7.0.1007_PV", which is an application, not a folder. Therefore, no .INF file. Intel does not offer a folder as was used in the tutorial: Promise Fastrak 376

 

Searching my Win 7 system, I see several of the type "amd64_amdsata.inf_31bf3856ad364e35_6.1.7601.21680_none_aaccc8deb1e48f1e", the differences being the chars after INF.

 

There is, on my Win 7 hard drive, a "readme.txt" file identifying "INFINST_AUTOL.EXE -or- INFINST_AUTOL.ZIP" that I interpret as sources of drivers for O/Ss including XP. It is not clear to me that this exe or the zip will not attempt updating, instead of just creating a folder similar to what the tutorial used.

 

Anyway, in Win 7 device manager:

 

IDE ATA/ATAPI controllers

Intel® Mobile Express Chipset SATA AHCI Controller

 

and clicking on the last above reveals:

system32\drivers\iastor.sys

 

Several versions of "iastorv.inf_amd64_neutral_668286aa35d55928", differing after the inf. Can't tell which is the one I need...unless I simply add all to the slipstream and let XP guess is the right one. [Note the "v" not appearing in the system32 line!]

 

It may be that there are no controller/driver files that will allow XP to install on an Acer Aspire 775oG-9411 as it is implied in the text on various websites that drives are O/S specific.

 

Thanks for any advice, even if it's: Ya can't get there from here.
