The system boots via PXE. That much is good. The host has two storage devices. This is a 16MB boot flash device that is soldered to the board. ad0: FAILURE - SETFEATURES SET TRANSFER MODE status=51 error=4< ABORTED> ad0: 15MB at ata0-master BIOSPIO This is a standard compact flash from Kingston. Many repetitive errors are snipped here. ad2: 1923MB at ata1-master UDMA33 ad2: FAILURE - READ_DMA timed out LBA=3940269 ad2: FAILURE - READ_DMA timed out LBA=3940209 ad2: TIMEOUT - READ_DMA retrying (0 retries left) LBA=0 ad2: FAILURE - READ_DMA timed out LBA=0 ad2: TIMEOUT - READ_DMA retrying (1 retry left) LBA=1 ad2: TIMEOUT - READ_DMA retrying (0 retries left) LBA=1 The flash drive is detected with 3940272 sectors. Is there a way to control the LBA= parameter? Does it matter if I try? How can I control the number of retries? I read that FreeBSD doesn't use the BIOS at least for CHS. Does FreeBSD use the BIOS for PIO and UDMA modes? Any thoughts on how to get these storage devices working? Thanks, Jason
