I have a Savage/IX agp card. Savage/IX was developed for
laptops so of its three possible output devices (LCD, CRT,
and several flavors of TV), by default it assumes that is
attached to a 640x480 LCD. Naturally this produces
undesirable results when a CRT is attached instead.
S3 provided a utility (s3switch) which allows choose which
output device or combination of output devices are attached.
This utility works fine with RedHat 8.0. It runs from the
command line or within X.
When I run it from the command line in FreeBSD 4.8-RC with
linux-compatibility in my kernel, the S3 utility fails
thusly:
vm86() failed
return = 0xffffffda
eax = 0x00004f14
ebx = 0x00000003
ecx = 0x00000001
edx = 0x00000000
esi = 0x00000000
edi = 0x00000000
ebp = 0x00000000
eip = 0x00004898
cs = 0xc000
esp = 0x00000ffa
ss = 0x1000
ds = 0x0000
es = 0x0000
fs = 0x0000
gs = 0x0000
eflags = 0x00003200
cs:ip = [ fb fc 80 fc 0e 74 48 80 fc 0c 74 46 80 fc 0d 74 ]
Can't change device (vm86 failure)
And this message is broadcast: "linux: syscall vm86old is
obsoleted or not implemented.
Tim Roberts has a similar utility, also called s3switch,
distributed as a linux binary and as source code.
When I attempt to run this binary from the command line, I
get:
Could not set device (vm86 failure)
Devices attached: CRT LCD TV
Devices active: CRT LCD
Current TV format is NTSC
And the same broadcast message as above. I have not run
this binary in RedHat 8.0, but I assume it will work there
as well as the S3 utility does.
Naturally, the source code will not compile on FreeBSD as it
includes a number of headers which don't exist in FreeBSD,
and according to Roberts' web page the utility depends on
vm86, from which I surmise there is no simple way to make it
compile and run on FreeBSD, with or without linux
compatibility.
Am I overlooking something that would allow either of the
binaries to work on FreeBSD?
