Newbie's got a dead 386

Hello all, FNG here. Having joined the mailing list a few days ago, I've been sitting back reading with interest and sometimes envy, but I have a prol'um: Friend brought me his expired Wyse Decision 386SX20 for resurrection. Don't know exactly why he brought it to me, just a somewhat adept hobbyist ( I only hurt myself every 45 min. or so). Guess he's too cheap to get a pro even though the unit is used as a POS device in his business. It's got a bad floppy drive, which I have, BUT, it sat around unplugged until the battery went down and the BIOS settings are GONE. I have tried every keyboard combination I can think of at bootup and I can't access the BIOS setup. I am suspicious that this model needs a special setup disk to write to the BIOS directly. No book, no brains, no patience...... this may take awhile. Any help would be appreciated. Thanks in advance. jax(a)tvec.net
