It is a 133 pentium system with phoenix bios 4.04. It depends. (Hi Dave!). Basically, you need to know why it is locking up under NT. If you disable the cache, does it work? If so, you will probably have to disable the cache under BSD and Linux as well, since it is likely that the cache is not being invalidated after bus mastering controllers have writtten memory regions that happen to be in the cache at the time of the transfer. Is it an IDE system? If it is, and you are using an RZ1000 controller, you won't have a problem under BSD. If you want to make it work under NT, you will have to disable queueing on the controller. This is generally a BIOS option. If you posted more information about the system, like chipset, controller, drive, and motherboard manufacturers, etc., you might get a response from someone with the same or similar equipment (and they could be more specific in their response).
