[parisc-linux] Re: pa-risc V0.9 on Model 720 (+ others)

[Michael S.Zick]

To All -

Reference my last on this subject - (attached)

Using xconfig as a model - on finds:

xconfig main menu
	network device support
		ethernet (10 or 100 mbit)
			EISA, VLB, PCI and on-board controllers

Selecting that choice would lead one to believe that the proper code 
for the "on-board controllers" would be generated.

Which should cover the built-in Ethernet on the older boxes (including
the standard, model 720) and when also combined with the proper selection of
card - a model 720 with an optional EISA BA having a Ethernet card plugged
into it.

Perhaps similar configuration logic could be included for the built-in (53c73xx)
SCSI controller - with the additional option of selecting an additional card
living in the optional EISA BA card slot.

Note: The prior owners of my machine had just such a configuration of on-board
and EISA bus SCSI controllers - running under HP-UX.

Only if you intend to never support non-PCI, non-EISA older boxes.

Regardless of your intent - proper combinations of CONFIG_xxxxx
are supposed to be handled by the (x)config step of the build process.
After all - that is what "configure" means (in English).

To do a clean job of this - a selection of "Box Model" (similar to "Processor Type")
may have to be added to the configuration scripts.  With corresponding #ifdef/#ifndef
statements in the relavent code.

At the moment - I have tunnel vision - I am focused on getting a personal copy
of parisc-linux to boot on my model 720 box.

The comments and findings I post to the mailing lists may be freely disregarded
by anyone not interested them.  Still, they will exist in the mail list archives so that
any developer working on a public version of this kernel can use them for hints, leads
and other ideas.
