PB Listas All This is quite a facinating group of threads that I've mixed up together, hope it's of some help. Longgg.

Now if I'm reading you correctly, you seem to be attaching drives to a booted and running PB, all such actions should be accomplished while the PB is fully shutdown and disconnected from any power, for if not you may be testing your luck on frying a port, or even worse. We've all heard of SCSI voodoo(more on this below) , but I wouldn't feel comfortable knowing really bad stuff could go down, if I do. The PB's PRAM is more than likely in need of all the former connected items to complete the boot, and in seeing a quite likely corrupted boot situation refuses to do so, until you rehook items. YMMV but, following a correct shutdown, wait for a few hours, cold reboot while zapping the PRAM. Will the ext. HD drive boot by using Cmd/Shift/Opt/Delete(docs) at startup, or directly following a full 3 gong PRAM zap to boot off the Ext. drive unit, if it's got a blessed bootable System folder installed on it? > > ------------------------------ > > From: mdstewart > Subject: 540c & 520c questions > > I'm new to the list.

There are a few PowerBook specific pages out there that will have 'bout everthin' ya ever wanted to know on them, do try a Google search for the O'reilly or O'grady PB pages, and look on www. lowendmac.com in the Powerbooks section found and followed from the right panel. > > My second question concerns the hard drive.

If you are going to be wanting to SCSI Disk Mode your PB to your DT Mac there is a limit to what size HD is installed, and if my memory doesn't fail here, it's in the 2 or 3Gb Max area, and if you go beyond that barrier things get very Bad n hairy real fast if SDM is employed, so if'n yer goin' the big HD route you are warned to never even think of trying a SDM hookup ever again until such a time that a smaller(within the limits) size HD is once again installed. > My fifth question involves Iomega drives.

Does the Zip have it's internal Termination switch set to on?, or have you externally Terminated it in some fashion? Actually, I really perfer using either a ZIP 100 or 250 SCSI Ext. drive sandwitched between PB and DT/MT units while using SCSI Disk Mode. > > My sixth question involves modems.

You'll need to score that well mentioned "C" PCMCIA cage to be able to try out the faster modems, again YMMV, what's the version of the cage in the 540 now?

Don't know about that, but stay tuned 'cause our GURUs are right here on this great list, just toss your ideas out here, and someone will likely pick up the ball and run the answer down to us, HTHs > From: "R.

Let's hope for the best here, and not the doodoo, do keep us in the loop on these happenings R.A., ok? > From: macnifico > Subject: CD sound thru PowerBook SCSI > > Hi, Listers!

Either the System's CD-Rom(or CD/DVD Rom) init, is loaded and working, or you've loaded another init driver from your Disk burning software that is diving the ext. drive, and it seems that you've got AutoPlay enabled in your perferences somewhere(which by the way, is not, or was not thought to be safe from a type of virus quite a few years back that used Quicktime's Autoplay/Start settings to begin it's nasty deeds. iirc > Can I do that with a less powerful computer, say a 1400, 3400 or 190? > Maybe even my old and trusty 540c? By all means do, you are only held back by the drives size in how much music you can load up at one time, there are even multidisk CD players out there which will play music non-stop for days on end if needed, like for those big all weekend long DJ-less parties, eh! > I had 9.04 on the PB WS, is this OS dependent? > Or is this feat dependent of the CD player or burner? As long as you can get your music onto the HD, or an attached drive, the PB's will be in effect a jukebox able to dole out vibes to your stereo, or power driven speakers, and even shared over a network by various means, there are various applications available for most OS versions, but if'n you've got lots of RAM to spare on a PPC PB go for the optimum of at least OS9.1 for it's stability, although you may want to trim the 68k code off of any FAT applications that're in regular use. iirc HTHs via condios Respectful of GURUs Bill Cornett cornett AT gol DOT com "Most of the people I know use Macs, and it feels like we're a privileged minority, though the odd thing is that, unlike Mercedes or BMWs, they are not significantly more expensive than the competition.Why does anybody use anything else?" -Douglas Adams Notice- I've gone in search of myself.
