There has been a limit in 386BSD 0.1, due to some sloppy programming. I remember that i had to patch the wdc driver so to use both, IDE and ESDI in the same machine. This has probably been the first machine on the world running this combination. In FreeBSD, this seems to have been fixed here: revision 1.19 date: 1994/01/04 20:05:23; author: nate; state: Exp; lines: +692 -574 New wd driver, based on Bruce Evans 'wx/altwd' driver which has passed enough tests to be considered more stable than current driver. ... Support for multiple controllers is in, but doesn't work correctly with different controllers (IDE AND MFM), but multiple alike controllers appears to work. ... ...that is, in FreeBSD 1.1. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
