I'm having trouble getting one of my IBM RT's to boot. It keeps trying to read from the floppy drive over and over, even though there's nothing in it. It should boot from the hard drives when there's nothing in the floppy drive. What should I do? -- Hugo Calendar ...!ucbvax!ucscc!spica!hugo CmpEng/Math Undergraduate 215 Weeks Avenue hugo@saturn.ucsc.edu IBM RT AIX/AOS/MACH Admin Santa Cruz, CA 95060 hugo@ucscd.bitnet Work Phone (408) 459-3224 USA (408) 425-5479 Above at University of California, Santa Cruz

Sounds like a problem with the disk adapter (probably the machine isn't "finding" the boot disk during POST), and you should call IBM Hardware at 1-800-IBM-SERV (1-800-426-7378). -- Michael Stefanik, Systems Engineer (JOAT), Briareus Corporation UUCP: ...!uunet!bria!mike -- technoignorami (tek'no-ig'no-ram`i) a group of individuals that are constantly found to be saying things like "Well, it works on my DOS machine ..."

Take the flopper out of it and see whether it boots. If it doesn't, it probably means either a boot block problem or a controller problem.

You did not say if you were running AOS or AIX, but on an RT running AIX, you CAN set the nvram to indicate the boot device. Under AOS, your milage may vary. :-) The following key sequences are documented in the VRM programming reference appendix C. The folowing keyboard key sequences only update the data in NVRAM. CTRL+ALT+a update nvram for diskette drive #1 CTRL+ALT+b update nvram for diskette drive #2 CTRL+ALT+c update nvram for fixed-disk device #1 CTRL+ALT+d update nvram for fixed-disk device #2 CTRL+ALT+e update nvram for fixed-disk device #3 These are other key sequences that are also defined: CTRL+ALT+PAUSE performs soft re-ipl of cpu. re-ipl vrm and initate ipl from default IPL sequence or from defined sequence set by CTRL+ALT+(a,b,c,d,e) CTRL+ALT+HOME perform re-ipl of virtual machines, does not re-ipl VRM. CTRL+ALT+'pad 6' Power-on-reset ipl. same as power on sequence. CTRL+ALT+'pad 7' perform VRM dump of real memory to floppy dump diskettes. CTRL+ALT+'pad 8' perfomr dump of selected areas of memory CTRL+ALT+'pad 4' invoke VRM debugger (if loaded) CTRL+ALT+END perform dump of first virtual machine. CTRL+ALT+DEL perform IPL of optional co-processor. CTRL+ALT+ACTION exits co-processor mode. This has gotten quite a few people over time. :-) Later, Markw -- Mark Whetzel My comments are my own, not my company's.
