This is something I was wondering when I bought the card. I tried to get the specs of the CMD649 chipset but they are not available at the manufacturer's site ( www.cmd.com). I took the risk because: 1- I believe bus mastering works on the AS200 (AHA, Tulip, etc.). 2- This board is supposed to work on Intel boards even without DMA support from the chipset. I cannot confirm the claim as I don't have such a motherboard. 3- Other known working device drivers do not seem different between platforms. The board has an EPROM and I suppose its code is not being executed; maybe it is necessary. I could make the disk work using an IDE ISA adapter, the device driver can see only 16 GBytes, the disk has 60Gbytes. > -----Original Message----- > From: owner-freebsd-alpha@FreeBSD.ORG > [mailto:owner-freebsd-alpha@FreeBSD.ORG]On Behalf Of Wilko Bulte > Sent: Monday, December 18, 2000 18:37 > To: Sergio Jachtchenco > Cc: freebsd-alpha@freebsd.org > Subject: Re: IDE CMD 649 and AS200-233 > > > On Mon, Dec 18, 2000 at 04:59:52PM -0500, Sergio Jachtchenco wrote: > > I could be completely offtrack here, but does bus master ISA dma work on > Alpha in the first place? > > Drew?
