583.0. "LINUX on PWS200i can't see PCI devices" by LEMAN::GABLER () Mon Mar 10 1997 09:27

	Hi,

I gave up trying to install LINUX on SCSI disk in my pws200i (note #578)

So i added an IDE disk and the installation succedded without any
problem on it.

The only remaining problem is that i can't see any PCI device. Here are
the messages i got in syslog :

...kernel: pcibios_init : BIOS32 Service Directory structure at
0x000fd5d0

       "        "       : entry in high memory, unable to access

       "        "       : no BIOS32 detected

What does it mean ? how can i get this to work ?

	Thanks for help

583.1	What version of the kernel are you using?	NEWVAX::PAVLICEK	Linux: the Truly Open O/S	`Mon Mar 10 1997 14:38`	1

	Well, I've located the source module on my Redhat 3.0.3/kernel 1.2.13 system (/usr/src/linux/arch/i386/kernel/bios32.c). As far as I can see, it is saying that the PCI table entries are located in the wrong memory area for the driver to access them. This may go back to the issue of shadowing that you raised earlier. Could one of the CMOS parameters be making a high-memory shadow of the PCI BIOS table? I'd go into your system CMOS setup and turn off any shadowing or caching that's enabled (AFTER writing down the current settings, of course! 8^) and see if the problem goes away. Maybe someone with a more substantial PCI background will have some insights here. -- Russ
583.3	Linux cannot recognize high memory PCI entries	LEMAN::GABLER		`Mon Mar 24 1997 09:22`	28
	Hi, I've got some more infos about that problem coming from Daves Heath (New Mexico State University). Can someone check if our problem is really related to this and if such a utility is available for our PWS200i. Thanks Clark ========= From: "D.Heath" <[email protected]> Hello, I am familiar with your problem but only with IBM type PCs. LINUX and Novell Netware cannot recognize high memory PCI entries so a third party utility must be used. I have found a DOS device driver called MOVEPCI.SYS provided by Compaq that is the fix for just this. It works. It moves the PCI entry to lower memory where it is properly detected by LINUX. The only drawback is that LILO cannot be used because the dos driver has to be loaded first....ie have to use LOADLIN. For your DEC 6200 a similar utility might exist. I am totally unfamiliar with DEC Personal Workstations though... Most all "moving-the-PCI" stuff was designed for Novell Netware Servers. LINUX is not really what they had in mind. Anyway, look into installing Netware on a DEC6200 and the solution to the PCI entry is probably documented. Hope this helps,
