Thank you for all of the replies:
Didier, the BIOS sees the SSD I disconnect it and it is not on the BIOS list. I reconnect it and the SSD is detected and correctly identified. I run the command (df), which asks for the available disk space, and it finds a 40 GB drive with very little space used at /dev/devtmpfs. Also, I can get the BIOS to boot from the SSD, but (fdisk -l) simply returns to the prompt, and (setup) complains that the disk is not partitioned.
Keefar, I have connected the SSD to both a blue and a gray socket, and there seems to be no difference. My SSD has a 3 GB SATA interface.
EDDY1, Yes you can disable a drive in the BIOS with on a Asus mobo. I did that for all of them and it took 2 hrs to figure out how to undo it.
I believe that I have corrupted the BIOS slightly and may have unmounted the SSD. At the moment, I can not get the BIOS to boot up from the SSD on reboot. It tries the DVD and quites. I can get into the BIOS and do it manually.
However, I have fixed the box by loading Mint 15. It works fine except for the reboot problem. In the process, the mint loader could see the Slackware on the SSD. I had the Mint loader remove Slackware, and will use Mint for a while. I am retired and 79 years old, it may be that I am just too old to Slack.
My thanks to everyone for their help, you are a great bunch of people.
