(Back in the days of SR-9.* you could even examine the keyboard SIO port parameters using "-line 0" with tea-kettle. ;) There are 5 signals: (DIN-8 connector) pin# Signal 1 V++ Power (+8.5V) 3,7 GND Ground 2 KBD_RESET Reset (active low) 4 KBD_RXD Receive data (to keyboard) 5 KBD_TXD Transmit data (from keyboard) (Yes it's a full duplex device, you can send it commands as well as receive data from it). The numbering scheme on that DIN-8 connecter is weird, it's not consecutive but hops back and forth in a strange star patter. The manual: Series 10000 Technical Reference Library, 011724-A00 Volume 5 -Hardware Specifications chapter 16 describes the keyboard hardware interface. The manual: Series 10000 Technical Reference Library, 011721-A00 Volume 2 -I/0 Devices Chapter 8 gives a detailed explanation of the data formats, keyboard codes, keyboard control commands, pointer device data codes, and keyboard programmable features. -- Dave Funk (319) 335-5751 Sys_admin/News-admin/cell_admin/Postmaster/Hostmaster for ICAEN Better is not better, 'standard' is better.

We have an HP433s here at Danford that has two disks, one with HP-UX 7.05 and one with SR10.3.4. It is possible to boot from either disk to get the operating system that you want. When the machine is booting in HP-UX mode, hit the space bar after the console beeps, it will ask for the specified bootable kernel (usually 1H - /hp-ux, or 1B - /SYSBCKUP). If you enter "DOM" it will put you in the Mnemonic Debugger (MD) and will allow you to "EX DOMAIN_OS" to start SR10. From MD you can boot HP-UX by entering "HP". There is also a "CF" configuration command at the MD level that will allow you to specify the default environment to boot from. I don't think that the boot ROM is special for our particular machine, so probably all HP433s have this ability. When ever you want to boot a different OS, you do have to change the keyboard. If you do not, the DomainOS will stall in the Phase II shell and you will not be able to type "go". The same thing happens for HP-UX, when the X-windows starts up it will complain that there is no input device. > Alan Katz, akatz@watertown-emh1.army.mil -- Bruce T.

Switch from Domain to HP-UX: At the MD prompt: CF 2 2 P E Switch from HP-UX to Domain: Interrupt the boot sequence by pressing until "Select System, type RETURN" and a question mark appears in the lower right corner of the screen C 3 1 P E But Britt Jensen has got a headless 425 that was switched to HP-UX. I don't know if it's possible to switch it back to Domain without a keyboard attached. Do you see the HP-UX boot messages on your serial terminal? Try to press at the terminal several times immediately after power on and see what happens. Lothar -- Lothar Paltins lothar@apollo.schwaben.de
