Driver Installation Requirements
3-3
Memory Requirement Scenario 1
There are two NICs installed. One has a maximum frame size
of 1514 bytes and four ELANs, and the other is a standby NIC.
The memory requirement is 24 megabytes of RAM.
Frame_Size = 1 (1514 bytes maximum frame size)
No. of NICs = 2 (two NICs are installed in the computer)
No. of ELANs = 4 (only one NIC has ELANs configured)
(16
1) + [(2 – 1)
(4)] = 20
The closest integral multiple of 8 greater than 20 is 24.
Memory Requirement Scenario 2
There are three NICs installed. One is a token ring LAN type
with a maximum frame size of 4542 and four ELANs, one is a
token ring LAN type with a maximum frame size of 9232 and
two ELANs, and one is an Ethernet LAN type with a maximum
frame size of 1514 and six ELANs. The memory requirement is
80 megabytes of RAM.
Frame_Size = 4 (use the largest value of all present)
No. of NICs = 3 (three NICs are installed in the computer)
No. of ELANs = 6 (the maximum number of ELANs on any one NIC)
(16 4) + [(3 – 1) (6)] = 76
The closest integral multiple of 8 greater than 76 is 80.
