3Com 905-tx Configuration

I. 3com 3c905-tx (3Com 905 prototype card BT leader) Configuration

905-tx .. prototype card, commonly known as: banniu card. Monster card. Grab wire king

8 KB cache, free partition: receive 5kb/send 3kb... receive 4kb/send 4kb... receive 6kb/send 2kb... etc.

"The prototype of the 905 series, one of the strongest and most severe immoral network cards, uses nonstandard parameters and does not have a random wait time. When a data packet collision occurs, the system immediately sends a data packet. The NIC obtains a latency of 2 microseconds, which is faster than 2.5 microseconds of 905b and 905c, and supports 2047 ultra-large data packets (this is blocked in 905b 905c) another important difference is that 905 is the 8 KB shared by the receiving and sending buffer, while 905b and 905c are independent channels for receiving and sending, each with a 2 K buffer, if we primarily use it for receiving at a time, should the shared buffer have a large capacity advantage? (8 KB) We generally share ADSL on the LAN, which should be used to receive more information. What is the bandwidth required to connect 905b 905c In the lan ?? "

3Com 905 series Introduction
The prototype of the 3c905-tx-----------905 series (with unknown functions) I used the original data volume the day before yesterday but it was found to be a prototype... Sent to friends...
3c905b-tx ------------ the first shard Store & forward function can greatly increase the number of valid packets
3c905b-txm ---------- the same as the above, but with the addition of the network traffic management function, and provides the 802-3q trunking Function
3c905c-txm ------------ the 3c905b quota that has been canceled is at least 1500 yuan cheaper than 3c905b. Currently, this is the market's major traffic source.

1: The 3c905 prototype card is used only for the HP compq server.

2: Each card on the network will throw a data packet. When both cards throw a data packet at the same time, a collision will occur. During the collision, the NIC will wait for a while and then re-Throw the data packet, if this random wait time is less, the NIC will have more transmission opportunities, which is higher priority than other NICs. So this is unfair, because the network bandwidth is certain, and there will be fewer people if there are too many, and the 3com905 series is like this, the network card that continuously gets the priority on the network. In addition, the 3Com Nic has many other advantages, such as good anti-interference and electromagnetic shielding performance, low heat consumption, low CPU usage, and low CPU usage during long stable operation .....

3: first introduce the famous network cards on the market:
3Com 905 Series
The prototype of the 3c905-tx-905 series is the network card of the wire King and the network card of the LAN.
No waiting time for the number of scrambling data packets is set. data packets are sent continuously. Nic acquisition time delay is 2 microseconds, ratio 905b, 905c2. fast in 5 microseconds, 2047 large data packets are supported (this is blocked in 905b 905c). Another important difference is that 905 is the 8kb shared by the receiving and sending buffer, 905b and 905c are independent channels for receiving and sending, each with a 2 K buffer. If we primarily use them for receiving at a certain time, the shared buffer should have a large capacity advantage (8 KB) generally, our local area network shares ADSL, which is used to receive a large proportion of data. The bandwidth of the 905b 905c card must be obtained in the LAN, but if it is not in the LAN, it will not have the advantage of the line, which is stable, with a low calorific value and will not be dropped. If you use this card, use BT to limit the speed.
3c905b-tx ------------ the first store & forward function of the chip can greatly increase the effective packet transmission volume
3c905b-txm ---------- same as the above, but added the network traffic management function, and provided the 80-3q trunking Function
3c905c-txm ------------ 3c905b deleted
Intel
82595 ---------- intel ee16 and eepro10 both use this chip to provide a speed of only 10 MB. However, they use two sets of DSPs to coordinate I/O buffer and I/O channel, which is the best among ISA NICs.
82557 ---------- this chip is used by Intel eepro100/eepro100b, which is the first chip of intel in the PCI interface network card, dec gave up its exclusive cooperation with 3Com to launch the server with this Nic, and was quickly eliminated because of its slow speed (chip clock ).
82558 ---------- intel eepro 100b/100 + all use this chip to quickly make it a favorite of server vendors, but it should not be available on the market at present, because most of the products are built in the motherboard instead of packaged with matching cards.
82559 ---------- Intel's next-generation network chip, mainly providing 802.3q support max X 4
82550 -------- the latest generation of chips on the market... Please check your own...

If many options are not available for 905-tx, install the driver first, restart the driver, and then install the above driver to crack all options.

1. Unzip 3Com windiags
2. Complete the solution for the next shard.
3. Upload the path of update.exe, and then start --> upload row, upload, and an empty grid. Add the cursor number/diag.
For example, you can directly store the D slot, that is, D: \ update.exe/diag (or use cmd to directly merge rows)
4. At this time, we can see the 3Com logo and update the driver!
5. Wait for him ................
6. At this time, you should see the beautiful music and the 3Com logo...
7. Start ---> there will be a 3com Nic doctor in the menu ...........
8. Find the candidate <-- has been optimized... select a maximize network performance!
9. Please refer to the example 1. Your 905 has been started !!!
