XP Pro -- which runs erratically (e.g., reboots) when the SSD drive is present.
Prior to adding the drive, I created and formatted an NTFS partition on the SSD using a different computer. The file system contains no data -- so the SSD should just appear as an empty 96GB drive.
But there are problems even before booting XP: The BIOS sometimes shows the correct size of the SSD (96GB), but sometimes shows a wildly incorrect size (many terabytes). Also, the BIOS "auto-detect" function, when selected, always hangs up (apparently indefinitely) even when the correct size is shown. (In both cases, the BIOS shows the correct name and model of the SSD, so at least that is working).
The BIOS has the latest firmware; and the latest Window XP SATA drivers (from Acer) are installed. However SlimDrivers reports newer SATA drivers are available, apparently from elsewhere, which I'm reluctant to try, especially given the erratic BIOS reporting.
The cabling looks good (SATA connections are easy).
I'm not using Acronis True Image, as I plan to do a clean install of XP on the SSD drive (and end up with a dual-boot system).
