[Qemu-devel] updated vqemu

["Jim C. Brown" <jbrown106@phreaker.net>]

[-- Attachment #1: Type: text/plain, Size: 766 bytes --]

This version supports using a config file in a place other than in the
current directory using the -config parameter. Use as:

vqemu -config config-file qemu-parameters

E.g.

vqemu -config ~/.vqemurc.minix -S

-config must be the first parameter to vqemu, and config-file the second.

Also vqemu supports the new -isa switch. If if you put PCI=off or ISA=on
in your config file, vqemu passes the -isa switch. The new default is to use
PCI.

If you're using an old CVS version of qemu that still has -pci, you can
set DEFINE_ISA_SWITCH=off (or any other value besides 'on') in the script
and vqemu will pass the -pci option UNLESS PCI=off or ISA=on in your config
file.

# DEFINE_ISA_SWITCH is used to tell whether or not our version of qemu
# supports the -isa switch. If it does we use that (and pci becomes
# default) if not we use -pci switch (and isa becomes default).
DEFINE_ISA_SWITCH=on
