The kernel should probe ATA for capabilities, then set a read-only sysctl variable, which could be tested by a piece of code in an RC script that would optionally set the atamodes to a more aggressive value. The user would be responsible for turning this feature, to set atamodes to more aggressive values if possible, on in rc.conf after installation. > > Jim Weeks > --------- A mind is a terrible thing to lose! How I miss mine... My problem is a little different than yours. Since I became a manager, I was given a choice of a lobotomy or another operation. The other operation would have given me a high voice, not to mention the excruciating pain, so I opted for the lobotomy.
