Hi: We are setting up a 32 machine distributed database system on AT&T 386 Unix workstations. They seem, so far, to be very quick robust machines. I will post some performance details about the machine type when we have our system operational and our benchmarks done. My questions are these: 1) We are stacking the machines 3 high and 10 wide. We are trying to find a way to enable the computers to boot up without a keyboard; i.e. diable the automatic keyboard check at boot time. Does anyone have information of a successful solution (or attempts) to this problem? We have thought about repressing the ROM to bypass the check or to make it more intelligent, and we have discussed building some chip in a box to simulate a keyboard. It doesn't matter if it is UNIX or DOS and I think the keyboard check is much like the one for the 6300 so ANY and ALL info along this line would be appreciated. 2) We have the tower upright version of the 386 workstation. I have been told that the console-unit's display is addressable by AT&T reps. Does anyone have the address and proceedures for displaying messages on the display?? Thanks very much, gray watson cgw@cadre.dsl.pittsburgh.edu

Does anyone have information of a >successful solution (or attempts) to this problem? The ROM BIOS listing provides details on what diagnostics checking is done on powerup, including the keyboard. Keep in mind that if you burn custom ROMs, the hotline won't support your machine. The keyboard does have some smarts so if you were to add a plug or box, it would have to be able to emulate whatever signals the keyboard sends back. There was a discussion about booting machines without keyboards in general in comp.sys.ibm.pc about 6 months ago I believe. I don't believe you can purchase ROM BIOS source in machine readable form. However, you can order it as a document. >2) We have the tower upright version of the 386 workstation. I have been >told that the console-unit's display is addressable by AT&T reps. Does anyone >have the address and proceedures for displaying messages on the display?? There was a discussion in comp.sys.att a while back (more than 6 months ago) about doing this. To be able to do this, you'll need to write a Unix driver for the console display, and then write code to send things to the adaptor. To do that, you'll probably need a 6386E WGS Processor Hardware Reference Manual (you'll also need to know how to write a Unix device driver). The documents I'd recommend are : 6386 ROM BIOS Listing (PEC 1637-021) $95 6386E Hardware Reference TBA 6386E Service Manual TBA The ROM BIOS listing is available now, the ROM BIOS is identical between the 6386 and 6386E (our listing covers the 1.13 ROMs, it may have been updated to cover 1.14's). The 6386E technical manuals aren't available yet, If there's enough interest I'll post ordering info when they become available. Hope this is what you were looking for. -- Frank McGee Tier 3 Indirect Channel Sales Support attmail!fmcgee
