There is no problem using the both drivers on either Linux or FreeBSD. On Linux, user can enter boot commands options in order to assign any cards to the driver it desires, providing the desired driver supports the board. This is not so easy under FreeBSD now, but I do use the both drivers at the same time on my box. The right direction is, in my opinion, to have drivers that allows users to get IN TIME functionnalities and performances they pay for. By the way, this not only requires development but also maintainance.=20 I have decided to have 2 drivers for the SYM53C8XX family and, as you should have known, nobody else seemed to have decided to do differently for _actually_ providing users features users pay for and not having to deal for a long time with to complex driver code. By the way, SYMBIOS did the same, independantly. G=E9rard. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
