Hi again, sorry for "replying" to my own message, but now the possibility of FreeBSD-2.2.1 to occupy this Big Box forever has grown to almost 100%... if only I knew the way to get FreeBSD recognize 2 PCI busses. :(( HEEEELP!!!! :) On Wed, 2 Apr 1997, Andrew Stesin wrote: > On Wed, 2 Apr 1997, Satoshi Asami wrote: > > > * 3. 2.2.1 has some problem with two PCI busses?

Now I can tell you what are the major (just biggest ones :) chips on the backplane, all have "INTEL" on them: 1. PCIset S82374SB (I suspice that this chip is a clue..) 2. PCIset S82375SB (gets recognized as 82375EB? EISA works anyway) 3. A|M|I 9637LZR (chip is (c)1994 Intel, no idea what's it) 4. XPC 637909-001 (no idea) 5. XPD 637910-001 2 parts (no idea) ... and Adaptec: 6. AIC-7870 2 parts (we all know them :) > > Boot with "-v" and send the output to se@freebsd.org. Just now I'm trying to boot a GENERIC with the increased size of vty' history buffer -- otherwise no way to catch all the messages esp. with "-v", PCI ones fly away, too many of them. Unfortunately, building a "true" FreeBSD boot floppy isn't so trivial. :( So no success yet... > > You may want to > > hack /sys/pci/pcisupport.c by yourself (grep for "IBM") to see if you > > can get it to work. I'm considering this, but I don't trust my own skills of hacking pretty unfamiliar kernel code to get production system running in 2-3 days... I still hope that there already is a solution...
