SYNOPSISdevice isa device snc
DESCRIPTIONThe driver provides support for the National Semiconductor SONIC Ethernet adapters.
HARDWAREThe driver supports the following cards:
- National Semiconductor DP83934AVQB
- NEC PC-9801-83
- NEC PC-9801-84
- NEC PC-9801-103
- NEC PC-9801-104
- NEC PC-9801N-15
- NEC PC-9801N-25
- NEC PC-9801N-J02 PCMCIA
- NEC PC-9801N-J02R PCMCIA
The driver also includes support for the National Semiconductor NS46C46 as 64 * 16 bits Microwave Serial EEPROM
IMPLEMENTATION NOTESAccessing SONIC card data structures and registers as 32 bit values makes code endianness independent. The SONIC is however always in big-endian mode so it is necessary to ensure that data structures shared between the CPU and the SONIC card are always in big-endian order. The driver supports the PC-98 C-Bus, and PnP buses. Support is also provided for the legacy C-Bus.
DIAGNOSTICSThe following driver specific error messages may be reported:
- "snc%d: snc_nec16_register_irq: unsupported irq (%d)"
- The card returned an IRQ which is not supported by the driver.
- "snc%d: invalid packet length %d bytes"
- An attempt to transfer a data packet failed due to an invalid packet length.
HISTORYThe driver was ported from Nx by An -nosplit An Motomichi Matsuzaki Aq [email protected] and An Hiroshi Yamashita Aq [email protected] . It first appeared in Fx 4.2 . This manual page first appeared in Fx 5.3 .

BUGSCurrently the driver only works on the PC-98 architecture. It should probably work on the i386 architecture as well.
