Hi
I want to run LinuxBIOS on an NCR-7456 POS PC. It`s mainboard is said
to be "Tiger MVP" (http://developer.novell.com/yes/75294.htm) and it
doesn`t seem to be on the SupportedMainboards list. However it`s
equipped with a VT8601A northbridge and VT82C686 southbridge. It also
has a 39VF040 flash chip soldered onboard. The northbridge is said to
be supported by LinuxBIOS but the VT82C686 has a question mark in the
SupportedChipsets table (for linuxbios v1) and isn`t mentioned at all
on the list of devices supported by LinuxBIOS v2. If so, what are the
odds of successfully running LinuxBIOS on this machine ? The BIOS flash
is soldered to the mainboard so it won`t be easy to reflash when
something goes wrong. If the southbridge chip (VT82C686) isn`t
supported what minimal code must be written for it to work ? I assume
that rs232 support is crucial for further development.
I have 2 of those machines, so I`m can experiment a little on one of
them. The second machine has already Linux installed (standard BIOS
though) and here is it`s lspci output:

I can also provide dmesg output, exact chip types, dmesg output and any
information that is neccessary. Unfortunately I didn`t find any
additional specs for this machine apart from marketing gibberish. But
I`ll keep looking.
