now for my questions:
a) can the VGA rom be loaded as some sort of payload, and thus be automatically added during the build process, or the described procedure here http://www.linuxbios.org/VGA_support is still the best way ?
that's still the only way for now.
b) is there any way to tell where the IRQ pins for each PCI device
are connected to the IRQ router chip?
schematics. Or a volt-ohm meter. In all too many cases, the IRQ table in the fuctory bios is wrong. It can not be trusted.
c) i built an irq_tables.c using getpir, but it didn't actually
helped much, as now i've got fewer devices working compared with the original bios :) (which i'm not that surprised at all) is getpir still the best method of detecting the original configuration?
I used to depend on getpir, until I found out how many bioses have the wrong PIRQ table, and then I found that after 2.4.18 Linux is parsing the IRQ tables incorrectly for cs5530, due to the fact that about half the GX1 tables in the world are wrong ... it is a terrible mess. So, getpir is only as good as the tables in the fuctory bios, which nowadays means ... maybe it will be good, but it is highly probable to have errors.
d) any other input you might give for help is welcome
nice work! how much did this board cost, and where do we get one?
Everyone, I think we can NOT delete the cs5530 support, or gx1 support in general; we have a new motherboard!
Luis, can you do an svn diff and post a patch to the list; or use the tracker?
thanks
ron p.s. your english is better than most US high school students :-)
