I have 2 of these controllers.. Just bought my second one for $40.00us on Ebay. They are a great device..
Heres what you do:
1.) Make sure the hardisk is set to ID 0 and termianted properly.
2.)Run the FaaastPrep program from the GVP install disk.
3.)Select "Manual"
4.)If it's talking to the drive, it should now show the configuration settings for the drive... Make sure it's set to "BOOT". Also, make sure the BootPri: is set to some reasonable value (like 1). If not, change it so that it is, and select "write".. This will write the config back to the RDB of the drive..
If you need the Install Disk, I can send you a .dms of it.
Also, I have the manual. If you cant find it on the web, I could scan it and upload it somewhere..
5.)Reboot and try again.
