Mr Perkins,

This modem (537) is a softmodem. This modem has no DSP.
Compared to the 536ep which is a controllerless modem which as a DSP chip.

The linux drivers for the 537 are in the final stages in being released.
I don't know the exact release date is but I believe it is soon.

Subject: Intel 537 Modem Info

I wanted to send this to put out information I had gathered 
regarding the mysterious Intel 537. Perhaps it 
will help someone Googling in the future.

1) The modem works, and configured OK as an Intel 537 modem 
in Windows FWIW.

2) The card is a 1/2 PCI card that came in an Intel box 
with the description "Internal 56K PCI Modem". There is a 
serial number, but no model number. Also included is a 
small paper manual with no manufacturer identified, and a 
CDROM with Computer Associates Bitware, Acrobat, drivers, 

3) The card has an FCC Registration Number of US: 
5RJFBOOBAMI-IA92. I couldn't locate additional info at the 

4) The board has IDs of "AMI-IA92/IE92", and 

5) The board has a sticker saying "Intel" over the main 
chip. The main chip is an Ambient MD3200 A (MD3200A?).
The chip also has the code "FC633-000 0206"

6) The modem appears to be available for sale at: I bought it at a 
surplus place in Minnesota.

7) When installed, /proc/pci says:
Communication controller: Tiger Jet Network Inc. Model 300 
128k (rev 0).
      IRQ 10.
      Master Capable.  Latency=32.  Min Gnt=1.Max Lat=128.
      I/O at 0xb000 [0xb0ff].
      Non-prefetchable 32 bit memory at 0xd9024000 

8) /sbin/lspci -vv tells us:

9) scanpci -v tells us the PCI vendor id, device id

10) Intel folks at are working on 
support for this modem.
