	Have you tried turning off Plug 'N Play support on the
card?

: tcm509: activate  (hang-up here, with the floppy LED is ON forever).

: My 3C509B has the feature as follows:

: Adapter type:                combo
: Date of manufacture:          6/13/95
: Division code:                6
: Product code:                 BZ
: I/O base address:             300H
: Interrupt request level:      5
: Boot PROM size:               disabled
: Transceiver type:             auto select


: On this 3C509B card, I'm also experiencing strange behaviour when I
: use the machine as a terminal with local disk of fully installed CDROM.
: At the boot time (still in CGA mode (I think in b.com mode), I can see
: the messages on the display as below:

: 2508 free pages, 10032K bytes, swap 52912K, highwater 500K, headroom 624K
: CPU is a 33 MHz Intel486DX (cpuid: ax 400 dx 0)
: ether0: 3C509: port 300 irq 5 addr 0 size 0 width 16: xxxxxxxxxxxx
: scsi0: aha1542: port 330 irq 11, dma 5,

: and after VGA mode,

: /bin/dossrv 21: serving #s/dos

: ipconfig: local IP address not found, IP not configured.
:             To use IP, edit /lib/ndb/local and reboot.

: Of course, I have 'sys' entry for this machine in /lib/ndb/local.

: This never happenes when I forced to set the sysname in /rc/bin/termrc,
: like sysname=andesite.

: Then, I looked into the source of /sys/src/cmd/ndb/cs.c, and I got
: the conclusion that it failed to get 'myetheraddr' from the 3C509 board
: (before the line 725 of cs.c (if(*ipa==0 && isether)).
: However, we can get the data from the b.com, as I showed above.  

: Therefore, I'm now doubting the 3C509B driver of the 9pc.  In fact,
: it's different from that in boot/pc.

: I'd be happy, if sopmeone could point me the real reason.

: Thanks in advance.
