I guess you need to disable ata dma before the installation begins. I can't see how to do that at the loader prompt (hw.ata.ata_dma isn't listed among the variables you can assign values to at the loader prompt) but maybe you can change to the holographic shell after getting into sysinstall and do it there. > > have the IDE drivers changed between 4.10 and 5.3? I assume so. I just had to set up a storage server with biggish disks and I used 4.10. There's clearly an issue in 5.3 with at least some disk drives (Maxtor > 200G crop up a lot when this problem is reported) and at least some ide controllers.
