1 $FreeBSD: releng/5.1/sys/i386/isa/README.le 50477 1999-08-28 01:08:13Z peter $ 2 3 ---------------- 4 5 This driver is in no way supported by Digital Equipment. See the 6 disclaimers in the sources for more. 7 8 This driver supports all the DEC EtherWORKS III NICs (DE203, DE204, 9 and DE205) and the later DEC EtherWORKS II NICs (DE200, DE201, DE202, 10 DE422). DEPCA-style boards prior to the DE200 have not been tested 11 and may not work. 12 13 This driver is not EISA aware. If you are using a DE422 or have 14 configured the EtherWORKS III in EISA mode, make sure you specify 15 the I/O port properly as this driver will *not* probe for it. 16 (The I/O port should be 0xNc00 where N is the EISA slot number). 17 18 This driver does not yet use the full 128KB allowed by the DE422. 19 Someday, it might. For EtherWORKS III NICs, the driver will override 20 the EEPROM setting of MemoryMode and *always* use the 2K for best 21 results. 22 23 The driver includes full support for both BPF and IP Multicast. 24 25 [All paths are relative to the top of sys source area, usually 26 /usr/src/sys.] 27 28 The following files need to be moved into their respective 29 directories: 30 31 if_le.c --> i386/isa 32 am7990.h --> i386/isa/ic 33 lemac.h --> i386/isa/ic 34 35 You will need to apply the patch provided in pat.files.i386 to 36 i386/conf/files.i386 file. 37 38 After that is done you will need to edit your config file (in 39 i386/conf) and a line similar to: 40 41 device le0 at isa? port 0x300 net irq 5 iomem 0xd0000 42 43 [The above line assumes the board is still at the factory defaults.] 44 Change the port, irq, and iomem value if needed to your configuration. 45 46 Now you are ready to rebuild your kernel, reboot, and see if the 47 driver can configure your board. When the system boots, you will 48 hopefully something close to: 49 50 EtherWORKS II: 51 52 le0 at 0x300-0x30f irq 5 maddr 0xd0000 msize 65536 on isa 53 le0: DE202 ethernet address 08:00:2b:2d:c8:45 54 bpf: le0 attached 55 56 EtherWORKS III: 57 58 le0 at 0x320-0x33f irq 5 maddr 0xd0000 msize 2048 on isa 59 le0: DE205-AB ethernet address 08:00:2b:bb:23:e0 60 le0 attached 61 62 in the startup log. If so, the board configured properly and 63 should be ready to use. 64 65 -- 66 Mail: firstname.lastname@example.org 67 URL: http://ftp.digital.com/~thomas/ 68
