I can/t really say how many companies are already following the legacy free
If you can find a computer without this "features" (and more important a
company who will tell you that) i would buy it.
Even Linus Torvald is working on this BIOS issue.
for instance -on my laptop for sure dont know ,again, how many of the new
models have already this- APM is out of buisiness, it will be replaced by
ACPI. ACPI for Linux (even if Intel itself is releasing the linux port) is
still far from being a serious working tool.
You could say what APM and ACPI has to do with IRQs? In legacy free computer
you must be able to assign IRQ from the OS itself. No way to disable PnP in
None of the traditional known ways to set up IRQs work...
I must say that beside the possibility of working with the internal sound card
and speaker for testing porpuses, we dont really want to work with it
professionally, so i guess PCMCIA cards should work (once driver exists...),
then the problem it is solved as wellas USB cards.
Of course all recent models tend to avoid "useless" outputs like: parallel
port serial ports. Only USB, USB everywhere...
AH and be carefull about internal modems....
Due to a new born...:-)) in the family i dint have time for much work a part
for changing diapers...but as far i know pratically all the features seem to
work with the toshiba satellite 5005-Sxxx.
DVD, CD writer, USB, PCMCIA, last one with different results. Also video
camera output and firewire are reported to work...
(not 100% sure about camera output and firewire)
The nice thing about the internal sound card would be the optical output
(supported by alsa...) but...untill the IRQ problem is solved there is no way.
I got the CD-Rom (audio) working by hadcoding the irq in the kernel
itself...and wav sound would play for a fraction of sound then it dies,
If i had to buy a linux laptop -right now- i would buy with a company that
support linux officially.
