Brief question for all you experts: Although it's harking back somewhat, I'm talking about 2.1.5 (WAAAAYY back). However, the issue I'm certain applies to recent versions too. I want to roll my own kernel, and up to 2.1.5, the only type of ISA controller possible was isa?, as per the following example: controller isa0 - under which you hung 8/16 bit device descriptions for ISA-based devices such as the console, keyboard, co-pro, floppy driver, disk controller, etc. With the advent of 2.1.5, the eisa controller support expanded possibilities somewhat, and support for my AHA 1742 moved under the EISA controller code. So here's the question; can I specify only the eisa? controller and have it control devices formerly under the isa? controller, or do I need to have both in there as seperate bus controllers, with the isa controller code probing and handling the ISA bus stuff and the eisa probing and handling the EISA cards? eg: Two bus controllers controller isa0 device npx0 device sc0 controller fdc0 device fd0 device fd1 .... etc. .... etc. .... etc. .... etc. controller eisa0 controller ahb0 device cd0 device sd0 eg: one controller controller eisa0 device npx0 device sc0 controller ahb0 device cd0 device sd0 controller fdc0 device fd0 device fd1 .... etc. .... etc. .... etc. .... etc. Can you Reply rather than post as I am unforch only subscribed to hardware and SCSI - and let's face it, this is after all an embarrasingly dorkish Q..... ;^) Rob -- Witticisms are hard to define on Monday mornings... schofiel@xs4all.nl http://www.xs4all.nl/~schofiel rschof@mccomm.nl
