SYNOPSIS:     Configuring the aha1542c with a Boot Drive > 1GB on x86 2.1

OS RELEASE:   2.1, 2.4 

PRODUCT:      Solaris X86

KEYWORDS:     boot reboot Adaptec aha1542c adapter


DESCRIPTION:

After successfully loading, the system attempts to reboot and issues the
following message:

     PANIC: aha_docmd: CDF won't go off for Data
     Press any key to reboot.


SOLUTION:

The aha1542c has a BIOS Translator to handle hard drives with cylinder
numbers greater than 1023.  This is for DOS only and must be disabled for
Solaris 2.1. 

Run the 1542c configuration program.  F6 Reset the 1542c.  This will
accomplish the necessary disabling of the BIOS Translation.  Then, setup
any non-default parameters that you require.  Save your changes, exit
and reboot Solaris.
