- The FAQ says that Linux won't run on EISA machines. Can anyone
- explain why, and suggest how difficult it would be to remedy ?
-
- That's not strictly true; if your EISA machine has a ISA floppy
- controller and a ISA graphics card plugged into, then Linux should be
- able to run on it without any problems. In fact, I think I remember
- someone reporting success with this configuration.
-
- The problem is that if you're doing this, there's really no point in
- your having shelled out extra $$$ for the EISA bus, since you wouldn't
- be able to use it.
-
- What's needed to rememdy this is that someone would need to write (or
- "borrow" from somewhere) device drivers that recognized EISA interface
- cards, particularily the hard disk and video interfaces.
-
- The same situation is true for the MCA bus, although that will be much
- harder, since MCA isn't even backwards compatible with ISA. At least
- with EISA, someone could borrow a ISA hard disk controller while he/she
- was debugging the EISA controller; thus development would be much easier
- under EISA than it would be under MCA. That's not to say that it
- wouldn't be possible to include MCA support as well; it would just be
- much more complicated. So I wouldn't hold your breath for MCA support,
- but EISA support is within the realm of possibility, assuming someone
- blessed with such a machine is willing to look at writing Linux drivers
- for these new controllers.
