Diagnostic Test Types
9-3
Group 1 Diagnostics
Group 1 diagnostics test physical components,
connectors, and circuitry of the 3C319 NIC as follows.
MMIO Register Write/Read Test
This test verifies that the PC can access the 3C319 NIC’s
memory mapped I/O registers correctly.
Boot PROM Test
This test verifies that the PC can access the boot PROM
correctly and verifies the integrity of the boot PROM.
AIP Checksum Test
This test verifies that the 3C319 NIC’s node ID, channel
identifier, and supported function identifiers such as data
rate, shared RAM, and transmit buffer size are correct.
Shared RAM Boundary/Domain Test
This test verifies that the shared RAM base address is
aligned on the proper address boundary according to the
shared RAM page size setting and verifies that its domain
does not conflict with that of the 3C319 NIC ROM.
Shared RAM Write/Read Test
This test verifies that the PC can correctly access the total
64 KB of available shared RAM.
Timer Test
This test verifies the 3C319 NIC’s timer operations by
comparing the 3C319 NIC timing to the PC’s timing.
Open NIC for Ring Operation Test
This test prepares the 3C319 NIC for a NIC ring operation
test and verifies the 3C319 NIC’s ability to transmit data
over the network. This test requires you to connect to an
STP or a UTP cable with a DAU, MAU, CAU, or token
ring switch at the other end.
