installing MKTK in SUN Ultra 20

Friends.
I´m triyng to install MKTK Router OS in a SUN Ultra 20 with SATA Disk Drive. This dont have the Legacy option to the SATA drive and can´t install because not a hard disk detect.

Have anybody a workarround for this.?
The SUN people don´t have idea.!

Muchas gracias

You must use Legacy in bios, otherwise the HD will not be detected…

if you do not have “legacy” option in your bios, you will probably have to use dedicated ATA or SATA card for PCI bus, they are very cheap.

Thank you friends… I solve with dedicated ATA Card.
