For what it's worth: I believe there is a compatability problem with the MCD PCI chipset. I have the Walnut Creek FreeBSD 2.1 CDROM and have installed the OS on a NEC PowerMate VP75. The machine contains an integrated dual channel PCI harrd disk controller. Primary Master is a 1.0G drive, Primary Slave is a 240M drive, and Secondary Master is a CDROM. Initial installation was done from a DOS-FAT partition. Subsequent CDROM access from FreeBSD results in a system hang which only a power reset will fix. The same problem occurred with OS/2 Warp and Windows NT 3.5. IBM's fix to the problem was the addition of two drivers (BASEDEV=CMD640X.ADD and BASEDEV=CMDATAPI.FLT) to overcome data read conflicts. These drivers disable the read-ahead mode for the RZ1000 and CMD640x PCI IDE chips. (Refer to Warp FixPak XR_W016.) This problem was also resolved in Windows NT 3.51. Incidentally, I could not install any packages from the FAT partition. It seems there is a character case translation problem in locating the files. In any event, A Great BIG Thank You to all who have made BSD available to the general public. I consider your efforts to be deemed as classical as Knuth's programming volumes.
