Mistreating it can cause +a number of effects -- everything from the card not responding when the +kernel probes, or the soft configuration being corrupted or wiped completely. + +By default, the kernel ships with device ed2 configured for the 'default' +Elite Ultra locations, comprising of port 0x300, irq 10, and memory location +0xcc000. This matches a hard coded jumper on the board as well a common +soft config setting. + +Unfortunately, the kernel's autconfiguration process (specifically, some +of the devices it probes for) cause conflicts with the SMC Elite Ultra, and +very often cause it to lose it's configuration and fail it's own probe. +If thise happens, you must boot the computer into DOS, and run the EzSetup +program available from SMC. The complete URL of which is +ftp://ftp.smc.com/pub/nics/ethernet/elite_ultra/gez122.exe. This program +will allow you to reconfigure and recover a card that has lost it's +configuration with a minimum of hassle. + +In order to avoid blowing away the card, one *must* use the run-time kernel +configuration system when booting the Install kernel. This is done by +giving the -c flag to the initial boot request. Following the loading of +the kernel, the user is presented with a + +UKC> + +prompt. At this prompt, as variety of commands may be issued, but the +relevant one to getting the SMC Elite Ultra running is 'disable'. The +wt0, el0, and ie1 devices all need to be disabled. This is done by typing +'disable' followed by the name of the device, i.e., 'disable wt0', and +pressing return. + +If, for some reason, your Elite Ultra is not configured at the 'default' +location the kernel is expecting it, you may also use the 'change' command +in the UKC system to modify where the kernel will look for it. Typing +'change ed2' will allow you to modify those settings. Note that running the +card at an i/o port of anything other then 0x300 at this point is not +recommended, and is beyond the scope of this document-- by doing so you +risk other device probes wreaking the havoc we are trying to avoid. + +When all three extra devices are disabled and any changes made, the +'quit' command will exit the UKC. The kernel should then boot, and find +your Elite Ultra on device ed2. |
