3Com EtherLink 10/100 PCI 3C905C-TX-M
Legacy PCI Fast Ethernet NIC with 3Com management/boot features. Confirm exact product label and revision before applying specifications.
IDENTIFICATION: Confirm manufacturer PID, hardware revision, device ID or module suffix. Nominal standards/link rates are not measurements of payload performance.
Exact specifications and compatibility
| Dedicated subcategory | Legacy networking adapters |
|---|---|
| Exact product/model | 3Com EtherLink 10/100 PCI 3C905C-TX-M |
| Bus, ports and physical interface | 32-bit PCI; one RJ-45 10/100BASE-TX port; optional WOL header on supported board. |
| PHY, radio or protocol | 3Com 3C905C-TX family; IEEE 802.3/802.3u auto-negotiation and full/half duplex depend on driver/peer. |
| Nominal rate (not measured) | 10/100Mb/s nominal Ethernet line rates; not measured throughput. |
| Measured throughput | No measured benchmark is claimed for a physical specimen. A valid result must record host/peer, link partner, media/cable, driver/firmware, traffic pattern, test tool and duration. |
| Drivers, OS and firmware | 3Com EtherCD/3Com NIC driver packages support historic Windows/NetWare releases; Linux 3c59x driver support depends on kernel; legacy package OS limits apply. |
| Compatibility | Requires 32-bit PCI slot, compatible driver and 10/100 peer; WOL may require cable/header and BIOS support. |
| Variant warning | 3C905C-TX-M differs from 3C905B-TX and 3C905CX-TX-M; label, controller revision and OEM subsystem ID determine driver and boot ROM features. |
