These errors are always related to geometry differences, so if disabling the extended translation (support for DOS drives > 1 gig option) doesn't work, you may have to play some other games to get the geometry right so you ca boot off of it. >- When I try to boot off of a bootfloppy distributed with the 2.0.5 cd, the >driver recognizes the card, reports the irq,dma,io, async only, parity, 32 >mbxs, 32 ccbs, whatever else.

It could be that the Buslogic is attempting to share an interrupt with another PCI card... assuming you have another PCI card in the system. Until 2.1-stable and 2.2-current, shared PCI interrupts were not supported for the bt driver. It may also be a dma channel conflict. I would suggest trying the driver in 2.1-stable if you can create boot media from it or can get a system up enough on your 1542B so you can genereate new kernels. With the 2.1-stable driver, you can disable all of the ISA compatibility features of the 946, and have the PCI BIOS do all of the setup for you (ie ISA dma channel/port address, etc). It could also just be that the I/O address, dma channel and IRQ defaulted to in the GENERIC 2.1R kernel are not appropriate for your setup. You might want to just try booting with '-c' and adjusting how the probe is performed. >Thanks in advance for your attention and help. > >Adam Prato > > >Adam R.
