I have a VLB card with a CMD640 (PCI0640B) chip for the primary IDE channel, and a Winbond chip for the secondary IDE channel. I heard some really bad things about the former chip corrupting data, and I wonder if this happens in every configuration or not.
Will it only happen if you have two devices connected to the same CMD640 IDE channel? Am I safe since I only have a CF card connected to the 640 (primary channel) and my CD-ROM connected to the Winbond controller?
I use MS-DOS 6.22 and Windows for Workgroups 3.11, and I don't use any CMD640 IDE drivers.
