So, does the RF gs/os driver ignores the gs/os cache completely? I mean, does it even matter if I have my gs/os cache on? Why don't Drew just keep a directory in RF's cache _all the time_? I mean, if he doesn't like the gs/os cache, let RF do the work then. What exactly is the 10mhz Hatachi used for? Maybe use it to manage the cache. frank m. lin fmlin@terapin.com
