Don't get too excited. I imagine that the SRM console's recognition of IDE devices is limited to those platforms which ship with Atapi CDROM drives. I think that's limited to DPWs. This almost certainly won't work on a multia. They show up as dkaxxx and dkbxxx on a DPW. I put a WDC AC31600H as the sole drive on the second IDE bus & saw this at boot: Digital UNIX V4.0D (Rev. 878); Mon Dec 29 20:10:32 EST 1997 physical memory = 64.00 megabytes. available memory = 50.61 megabytes. using 238 buffers containing 1.85 megabytes of memory ... ata1 at pci0 slot 207 ata1: Cypress 82C693 scsi1 at ata1 slot 0 rz8 at scsi1 target 0 lun 0 (LID=0) (WDC AC31600H 23.1) .... The disk labels & newfs just fine and can be used as a boot device. Performance is crappy, but no worse than the same drive in an intel with the most conservative ide settings in a FreeBSD kernel(eg, no flags on the wdcX kernel config line).
