Yes the setup is a two disk striped raid array which shows up correctly as three partitions and unallocated space.

As an aside, can I slipstream one of the working test MassStorage packs into BartPE (for UBCD4Win) and see what that produces when built?   At the moment in DPs_Base the pack shows as current in the 'check for updates' section but is greyed out on the 'Select DriverPacks to Slipstream' section.

Pack 13=4 instances of Unknown Disk (there is no disk in this drive)
Pack 14=4 instances of Unknown Disk (there is no disk in this drive)
Pack 15=4 instances of Unknown Disk (there is no disk in this drive)
Pack 16=4 instances of Unknown Disk (there is no disk in this drive) then BSOD after F3 to quit
Pack 17=4 instances of Unknown Disk (there is no disk in this drive) then BSOD after F3 to quit
Pack 18=4 instances of Unknown Disk (there is no disk in this drive)

All BSODs, as far as I remember, from setupdd.sys.

My computer did not explode.

Each test cycle took 10 minutes to complete, including two reboots of the PC.

I hope that this testing is of use to you.

Here's the next lot:

Pack  7=4 instances of Unknown DIsk (There is no disk in this drive)
Pack  8=4 instances of Unknown DIsk (There is no disk in this drive)
Pack  9=4 instances of Unknown DIsk (There is no disk in this drive) then BSOD after F3 to quit
Pack 10=Success
Pack 11=Success
Pack 12=4 instances of Unknown DIsk (There is no disk in this drive)

My ice cream is still solid.

I'm using the first 2 of the 4 SATA connections as a striped raid array.
Device manager has the raid controller as ACPI\NVRAIDBUS\3&267A616A&0
and 2 NVIDIA nForce Serial ATA Controllers PCI\VEN_10DE&DEV_03F6&SUBSYS_82341043&REV_A2\3&&267A616A&0&40

The DVD is on the PATA interface.

The other queries will be harder to sort out as the PC on which I run the tests is also my business machine so I can only go as far as the windows setup screen to see if partitions are visible.   To get further I would have to build a new XP setup on a new partition of the hard drive, I'm not sure what that would do to my existing dual boot with Windows 7, I'd have to check first.

Here are the HWIDS, OS details and the results of testing packs 1 - 6.

Windows XP Home SP3

Pack 1=4 instances of Unknown DIsk (There is no disk in this drive)
Pack 2=4 instances of Unknown DIsk (There is no disk in this drive)
Pack 3= success
Pack 4=4 instances of Unknown DIsk (There is no disk in this drive) then BSOD after F3 to quit.
Pack 5=4 instances of Unknown DIsk (There is no disk in this drive) then BSOD after F3 to quit.
Pack 6=4 instances of Unknown DIsk (There is no disk in this drive)

The cat is still black and white!

More results soon.

Yes I can try those packs for you, I've downloaded the file of 18 NVIDIA packs.   I report back in batches including the hwids, driver and OS details in the first one.

I use an ASUS M2N based PC running XP SP3 and was trying to create a working slipstreamed boot disc but without success.   I found the post about edits to setupreg.hiv and applied it, but still no success, no raid array visible.

Expanding MassStorage pack (10.11) led me to subdirectory N7r which contains the same files that I had downloaded from ASUS.   Copying these to a floppy disc (yes I still have one), booting from an XP issue CD and doing F6 thing found the raid array, so I know the section is correct.

Checking the i386 directory in the slipstreamed output showed that though nvgts(5/6/7).sys were present nvgts.sys was not.

The nvgts.sys driver does not appear in DriverPacks_MassStorage_wnt5_X86-32.ini but is in nvrd32.inf in directory N7r.

Directory N7 contains nvgts.sys and nvgts7.sys.

Running Microsoft's checksum (fciv) utility on each of the above nvgts*.sys produced the same answer, I haven't checked nvgts(5/6).sys.

Any suggestions for a fix would be greatly appreciated, thanks.
