Note:   If your Linux kernel is 2.4.x or above then do not use these instructions. See knowledgebase for PCI-Fast and Linux 2.4.x installation.

Instructions: 
Power down your Linux server.  Insert the PCI-Fast card in your system and power up. Logon to Linux Server and issue the following command:  cat  /proc/pci
Your system’s pci entry for the PCI-Fast card should appear similar to the following example before you can continue with the installation.  This ensures that your system’s PCI BIOS has assigned resources to the
PCI-FAST card.  The actual resources will differ between systems.  

Serial controller: PLX PCI9050 I2O (rev 1).
Medium devsel.  Fast back-to-back capable.  IRQ 11. 
Non-prefetchable 32 bit memory at 0x41000000 [0x41000000].
I/O at 0x1000 [0x1001].
I/O at 0x1080 [0x1081].

Now that the card has been detected and assigned resources, install the PCI-Fast card driver version 2.02. You can use the driver version 2.02 from the CDROM supplied with the PCI-Fast serial card.  

Mount the CDROM.  For example,  mount  -t  iso9660  -r  /dev/cdrom  /cdrom

Make the chase directory then copy the Chase driver from the CDROM to the chase directory. For example,   

mkdir  /chase
cp  /cdrom/pci-fast/drivers/linux/atpc_202.dd   /chase

Change directory to /chase and extract the Chase driver. For example,

cd  /chase
tar  xvf  atpc_202.dd

From the /chase directory type:    ./install

Answer all questions related to your environment.  For example,  

· Are you ready to continue (y/n)  select  y.
· How many AT-FAST cards to install [0]   ('o' since this is a PCI-Fast card)
· Automatic or manual entry?  (a/m)  select 'a'  for automatic. 

Configure the kernel to include built-in support for the Chase PCI-Fast card. For example, 

cd  /usr/src/linux
make menuconfig

· Scroll down to 'Character Devices' and choose the select  option.

· Scroll down to line and select 'Chase Research AT/PCI-Fast and PCI-RAS support'.
 
·Exit the menuconfig screens and answer 'yes' when prompted with "Do you wish to save your kernel configuration".

Rebuild the Linux kernel. For example, 

From the  /usr/src/linux directory,  type the following. Note the upper case  I  in bzImage.

make dep;make clean;make bzImage 

Once the rebuild has successfully completed, overwrite the old kernel image with the new kernel image.  For example,  

cp  /usr/src/linux/arch/i386/boot/bzImage   /boot/vmlinuz

If using  lilo, update the loading map by typing:  /sbin/lilo

Reboot the Linux machine by typing:  reboot

Done. 

Note:  TTY device names that are automatically assigned to the PCI-Fast serial ports are: 

ttyCH0 for port1, ttyCH1 for port 2, ttyCH2 for port 3, and so on... depending on whether you have a 4, 8, or 16 port PCI-Fast card.

You may need to changes permissions on the devices. 
For example,  chmod 777  /dev/ttyCH*   or   chmod 777 /dev/cuch*

------------------------------------------------------------------------------------------------------------------------------

OPTIONAL  -  Adding logins for tty devices

Add a login entries in the file  /etc/inittab.  Each port requires a
login entry.  For example,

ch1:2345:respawn:/sbin/getty ttyCH0 DT9600
ch2:2345:respawn:/sbin/getty ttyCH1 DT9600
ch3:2345:respawn:/sbin/getty ttyCH2 DT9600
ch4:2345:respawn:/sbin/getty ttyCH3 DT9600
.
.
and so on...  depending on whether you have a 4, 8 or 16 port PCI-Fast card. 

Note: The speed label definitions (for example, DT9600, DT19200, DT38400) are found in the file /etc/gettydefs.  (For example,  DT9600 specifies 9600 baud, 8 data bits, 1 stop bit, no parity, software flow)

Update the entries in the file  /etc/inittab by typing the following command:    init q

At this point, logins should appear on the attached attached serial display devices.

Other useful information

· To remove the Chase driver, type  ./remove  from the chase directory.

· System start-up messages are logged in the file  /var/log/dmesg   or   /var/log/messages

· The Chase PCI-Fast card resources are logged in the file  /proc/pci

Some troubleshooting TIPS

For PCI-Fast cards,

· You may need to adjust your BIOS settings on your Linux Server to free up resources such as disabling built-in devices. 

If there is no login response on the terminal however the PCI-Fast serial card appears in  /proc/interrupts  and  /proc/pci  and a login process is running on the Linux Server, do the following:

· Verify the cable specifications used between the PCI-Fast serial port and the terminal. Refer to the Installation and Configuration guide for cable diagrams.

· Verify the Terminal settings match the line settings of the PCI-Fast serial port. The default is 9600,8,n,1,xon/xoff.  Line settings can be changed in the file  /etc/inittab.
