/* Probe for various non-shared-memory ethercards.
|
|
|
|
NEx000-clone boards have a Station Address PROM (SAPROM) in the packet
|
|
buffer memory space. NE2000 clones have 0x57,0x57 in bytes 0x0e,0x0f of
|
|
the SAPROM, while other supposed NE2000 clones must be detected by their
|
|
SA prefix.
|
|
|
|
Reading the SAPROM from a word-wide card with the 8390 set in byte-wide
|
|
mode results in doubled values, which can be detected and compensated for.
|
|
|
|
The probe is also responsible for initializing the card and filling
|
|
in the 'dev' and 'ei_status' structures.
|
|
|
|
We use the minimum memory size for some ethercard product lines, iff we can't
|
|
distinguish models. You can increase the packet buffer size by setting
|
|
PACKETBUF_MEMSIZE. Reported Cabletron packet buffer locations are:
|
|
E1010 starts at 0x100 and ends at 0x2000.
|
|
E1010-x starts at 0x100 and ends at 0x8000. ("-x" means "more memory")
|
|
E2010 starts at 0x100 and ends at 0x4000.
|
|
E2010-x starts at 0x100 and ends at 0xffff. */
