3C515-TX NIC Operation Tips
3Com testing has discovered bus mastering problems on
some PCs. Refer to the README.TXT file for information
on how to disable bus mastering.
The 3C515-TX NIC was designed for maximum
performance and compatibility in ISA-only machines. For
PCI/ISA hybrid or EISA PCs, use the 3Com 3C905-TX
Fast EtherLink XL PCI NIC or the 3Com 3C597-TX
Fast EtherLink EISA NIC.
Compaq 386/20e PC
3Com has observed during testing that the 3C515-TX
NIC is not detected by the Compaq 386/20e PC.
Compaq DeskPro 433/L PC
The Plug and Play (PnP) range check cannot detect an I/O
conflict with the on-board video set to the 0x3C0 I/O
base address. This NIC works with other I/O base
address settings.
IBM 486 SLC and IBM 386 SLC PCs
The 3C515-TX NIC does not run in bus master mode on
these PCs. To disable bus mastering on your PC, refer
