Hi!
I have installed FreeBSD 8.0 on my old Toshiba Satellite Pro 4600
laptop with 256 MB RAM and it's running pretty good.
The laptop has an internal modem.
When I issue 'pciconf -lv' in the shell I get:
...
none0@pci0:0:31:6: class=0x070300 card=0x00011179 chip=0x24468086
rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = '82801BA/BAM (ICH2/ICH2-M) AC'97 Modem Controller'
class = simple comms
subclass = generic modem
...
I can't find a driver for it for the FreeBSD system.
Do you know where I can find a driver for it?
Or is there any way I can get the modem working, with another general
driver or something?
Thanks in advance!
Elton
The only way your going to get that internal modem to work is run
an older version of Linux on it. FreeBSD does not have a driver for
that and never will, at this point. FreeBSD used to have 2 modem drivers
for softmodems, one was for the Lucent chipset and the other for the
Conexant HCF chipset. But the changes in FreeBSD 8.0-RELEASE
broke both those drivers. Incidentally both these drivers were "wrapper"
drivers, they used binary blob drivers (windows or Linux I forget which)
Supposedly the chipset on your AC97 controller is a Lucent chip
but the old FreeBSD driver was for the MC97 not AC97 controller.
An early beta of FreeBSD 8, before they changed the serial uart
routines, did work with the Lucent driver if you patched the driver - but
the later changes broke it.
I contacted the developer who put in the uart code to FreeBSD and
apparently he was under a contract to do it - perhaps the FreeBSD
Foundation paid him - and he had absolutely zero interest in porting
the Lucent driver over.
The problem now is that there isn't enough call anymore for modem
drivers.
Your Satellite has a "real" serial COM port on the back and so your
best option to get a modem working under FreeBSD 8 is to use a
real serial cable and buy an external hardware modem. There are tons of
them
out there gathering dust in computer scrap dealers and such.
If your bound and determined to get the internal modem running then
read this:

Needless to say it's obsolete now - but the info in there on the modem
section illustrates the difficulty of getting these winmodems working.
