The Design and Implementation of laffer1

I sent caryn an email about the ptr record for our mail server. Hopefully comcast will switch that for us.

I drove back from ann arbor today. Work is VERY slow. I had 3 calls and now i'm sitting on my ass. Wanted to work on the server but lost ssh access to it during a make installkernel

I've been trying to determine why my FreeBSD Sparc64 install only supports WDMA2 (16mb/s) with the CMD PCI0646U IDE controller.  According to various google results, the IDE controller is extremely buggy and does not properly initialize itself.  There are several undocumented features and the vendor does not want to release the information.  As a result, the card is marked as broken and degraded to WDMA2.  It theoretically can support UDMA33.  I do not know how fast it runs on solaris.  OpenSolaris may provide clues...

NetBSD introduced a flag in the kernel to enable Ultra DMA 33, but cautions against it pointing to the linux developers observations.  I've previously hacked on some FreeBSD SATA code and may need to do the same here.  Its worth trying UDMA33 before I put the machine into production. 

The CMD PCI0646U2 supposedly can be hacked around and made to work properly.

On a side note, it appears solaris 2.6 can't address a 120gb disk even though most suns from the era can handle up to 137gb disks (ultra 5s and higher) .  I've got a working FreeBSD sparc64 6.0 install with an 80gb disk and had solaris 10 working fine on my ultra 10.

Hmm. U of M flint cashed the check so i'm just waiting on KVCC. 5 days my ass.
