I found a workaround. The problem was that the ata driver dma mode was corrupting disk write/read on my computer. My IDE controller is a VIA VT82C693A or VT82C596B (not sure which one, both codes are listed), onboard a Asus P3V133 motherboard. After I figured that out: I booted from the installation CD-ROM, started a emergency shell and issued the command "sysctl -w hw.atamodes=pio,---,---,pio" (hard-drive primary master,cd-rom secondary slave). Then it installed ok. But on every boot from the hard drive I need to boot_single and do the sysctl again before starting to write on the drive. Then I compiled a new kernel using the wd driver. Works fast and is reliable. Thanks for your attention. --- sheldonh@FreeBSD.org wrote: > Synopsis: Unable to install.
