IRQ Level

Select an interrupt level for this adapter card.

IRQ is a hardware line which is drien by one or more hardware devices indicating to the CPU that the hardware device needs attention from the software.  The IBM PC has 16 IRQ lines going into a PIC (Programmable Interrupt Controller).  The PIC interfaces with the CPU.  The CPU is supposed to call predefined software routines when the interrupt is generated.

For Ethernet+Modem devices, the IRQ Level specifies the IRQ for both the Lan side and the Modem side of the driver.


I/O Base

Select an I/O Port for this adapter card.

I/O address is the address of any hardware device register which is mapped in the I/O space of the x86 microprocessor.  The x86 microprocessor has 64K bytes of I/O space and different devices can use the I/O space to map their registers.

For Ethernet+Modem devices, the I/O Base specifes the network I/O address. See Com Base for the I/O address of the communications device.


Media Type

Select the media type for this adapter card.  The default is 10BaseT.


Network Address

Select 12 hexadecimal digits.  The address must specify the "locally administered" bit on and the "group" bit off.  In other words, the two low order bits of the high-order byte must equal the value 0x02.  Each adapter on the network must have a unique network address.  The default value is the burned in address contained in the adapter.


COM Base

Specifies the Com Port (Com1 thru 4) I/O Address.  You must also select the Ports dialog from the Control Panel and the the proper COM port with the values selected here.


Continue

Select Continue to save the values defined in the dialog box and exit.
