It is still stupid if you disable 32 bit disk I/O. You *must* disable 32 bit disk I/O if you don't have a BIOS option to disable interleaved I/O *and* you have an RZ1000 based controller. Ie: you *must* make it stupid if you have an RZ1000 and either don't have an advance BIOS option or are afraid to edit it. Which is most people with the 1/3 of all E/IDE controllers. Typically, you'd just hit OnTrack (or the one Seagate ships) before booting Win95. Since it ships as an "upgrade only", you'll be booted with the INT 13 redirector in place and it will be transparent. But this is a FreeBSD list. 8-).
