During the boot proccess I 've got these messages acd0: CDRW at ata1-master UDMA33 acd0: TIMEOUT - READ_BIG retrying (2 retries left) acd0: FAILURE - READ_BIG timed out acd0: TIMEOUT - READ_BIG retrying (2 retries left) acd0: FAILURE - READ_BIG timed out acd0: TIMEOUT - READ_BIG retrying (2 retries left) acd0: FAILURE - READ_BIG timed out acd0: TIMEOUT - READ_BIG retrying (2 retries left) acd0: FAILURE - READ_BIG timed out acd0: TIMEOUT - READ_BIG retrying (2 retries left) acd0: FAILURE - READ_BIG timed out acd0: TIMEOUT - READ_BIG retrying (2 retries left) acd0: FAILURE - READ_BIG timed out acd0: TIMEOUT - READ_BIG retrying (2 retries left) acd0: FAILURE - READ_BIG timed out After waiting for a long time the TIMEOUTS, I finally got in the sysinstall screen and the installation stopped at the point where new packages had to been added to my new system. I reboot the system and I continued the installation from FTP, altough the safe mode option didn't have any problem with DMA issues. At the end when the installation was complete, it was impossible to mount any cd/dvd disk. The problem was solved by passing to the /etc/loader.conf this line hw.ata.ata_dma="0" and everything gone well. I could mount any cd/dvd disk without any problem. It will be grate if this problem is solved in future releases, cause it is very discouraging for a new user to have such boot messages in his first installation effort, even if it is unlikely for someone to have the same, fine tunned to the problem, hardware. For any further information please feel free to contact me. Kostas Theofilatos ps: In order to install FreeBSD 5.3 Release to box with the same symptoms like mine (without using FTP or safe mode) it is enough for someone, to press "6" and escape to the loader prompt before the kernel loads, and then give set hw.ata.atapi_dma=0 boot The further installation will go as expected...
