Submitted by: Thomas David Rivers <rivers%ponds@ncren.net> WARNING: might hide some bug below! I commit this to improve the stability of 2.0.

I re-read wd.c, and added appropriate printfs() to look for references to dk_badsect[]. My changes should have printed something when dk_badsect[] was referenced. I got no output :-( Thus, I'm forced to concluded that something else is examining some spurious memory... which happened to be in dk_badsect[] of the disk structure in wd.c. I can find no other explanation of why this unnecessary initialization causes things to operate correctly. On the premise that such an initialization isn't going to hurt anything, I'm going to suggest it go into 2.0. I'd like to thank everyone for there assistance, particularly David, John and Bruce.
$Id: README.le,v 1.1 1994/08/16 20:40:56 thomas Exp $ ---------------- This driver is in no way supported by Digital Equipment. See the disclaimers in the sources for more. This driver supports all the DEC EtherWORKS III NICs (DE203, DE204, and DE205) and the later DEC EtherWORKS II NICs (DE200, DE201, DE202, DE422). DEPCA-style boards prior to the DE200 have not been tested and may not work. This driver is not ESIA aware. If you are using a DE422 or have configured the EtherWORKS III in EISA mode, make sure you specify the I/O port properly as this driver will *not* probe for it. (The I/O port should be 0xNc00 where N is the EISA slot number). This driver does not yet use the full 128KB allowed by the DE422. Someday, it might. For EtherWORKS III NICs, the driver will override the EEPROM setting of MemoryMode and *always* use the 2K for best results. The driver includes full support for both BPF and IP Multicast. [All paths are relative to the top of sys source area, usually /usr/src/sys.] The following files need to be moved into their respective directories: if_le.c --> i386/isa am7990.h --> i386/isa/ic lemac.h --> i386/isa/ic You will need to apply the patch provided in pat.files.i386 to i386/conf/files.i386 file. After that is done you will need to edit your config file (in i386/conf) and a line similar to: device le0 at isa? port 0x300 net irq 5 iomem 0xd0000 vector le_intr [The above line assumes the board is still at the factory defaults.] Change the port, irq, and iomem value if needed to your configuration. Now you are ready to rebuild your kernel, reboot, and see if the driver can configure your board. When the system boots, you will hopefully something close to: EtherWORKS II: le0 at 0x300-0x30f irq 5 maddr 0xd0000 msize 65536 on isa le0: DE202 ethernet address 08:00:2b:2d:c8:45 bpf: le0 attached EtherWORKS III: le0 at 0x320-0x33f irq 5 maddr 0xd0000 msize 2048 on isa le0: DE205-AB ethernet address 08:00:2b:bb:23:e0 le0 attached in the startup log. If so, the board configured properly and should be ready to use. -- Mail: thomas@lkg.dec.com URL: http://ftp.digital.com/~thomas/
