I finally succeeded in completing what I had in mind.
The bottom line is that the ASUS P5LD2-VM Motherboard is geared towards S-ATA disks and it doesn’t appear to favor P-ATA. It has two IDE connectors and four SATA. Actually the blue IDE is for 100/66 IDE devices (probably aimed at optical drives). The red one is for UDMA up to 133. It is supported by an ITE 8211 Controller. Connecting the lone old System disk (XP-SP1) on either one ended up with a 7B message in a BSOD screen.
1. I slipstreamed an XP-SP2 installation cd (I learned that the built-in repair install feature was not available on SP1). I extracted to diskette from the defective Asus cd-rom all items linked to XP ITE.
2. I connected the lone old System disk to the red connector. I launched the install process from the slipstreamed cd and pressed F6. The ITE drivers from the diskette were used further on.
3. The installation succeeded all the way first time through despite new motherboard and I recovered all initial programs and features from the old environment. I just had to update from the Asus cd some of the drivers unavailable (or outdated) in XP-SP2.
As a fallback procedure, I had this gadget which allows you to connect an IDE disk to a SATA plug on the MB.
Thanks to all for for suggestions provided
