You don't say which Boca it is... But if it is the
IO/AT66, you set it up with a single interrupt
that is shared by all ports. You then use
"setserial" in your /etc/rc.d/rc.local to assign
the memory addresses or you can edit serial.c to
the proper settings (You don't need anything in
lilo).
Look for this section in serial.c:
{ 0, BASE_BAUD, 0x100, 12, BOCA_FLAGS },/* ttyS16 */
{ 0, BASE_BAUD, 0x108, 12, BOCA_FLAGS },/* ttyS17 */
{ 0, BASE_BAUD, 0x110, 12, BOCA_FLAGS },/* ttyS18 */
{ 0, BASE_BAUD, 0x118, 12, BOCA_FLAGS },/* ttyS19 */
As you can see, the driver defaults to starting at
memory address 0x100 and IRQ 12. you can change
these settings with "setserial" to match the
boards settings. The board should have a jumper to
set the starting memory address.
Here is a snippet from rc.local:
setserial /dev/cua4 uart 16550 port 0x180 irq 10
setserial /dev/cua5 uart 16550 port 0x188 irq 10
setserial /dev/cua6 uart 16550 port 0x190 irq 10
setserial /dev/cua7 uart 16550 port 0x198 irq 10
setserial /dev/cua8 uart 16550 port 0x1A0 irq 10
As you can see, the memory address and IRQ can be
changed here to match the boards jumpers so you
don't have to re-compile the kernel.

The PCI interface card is about $450 and each 16
port module is about $550. This is an intelligent
board and can high baud rates on all ports.

What board?
Who's driver?
What kernel?
