They do have buffers, 512k and 2 mb are common, with the trend going back to 512k. That is something just less than a second, but apparently if something is going to glitch for half a second most likely it will nail you even with a two second buffer. I think you are correct though that the driver stuff may be snafu. I wonder if the W95 installer maker will even do something on a CDROM, or is it just for floppies?
