Wallstreet, funny noise after startup tone

You may need to install a firmware update before installing OS X. See Mac OS X: Available firmware updates
http://docs.info.apple.com/article.html?artnum=86117 This update must be installed using OS 9.

Tom,

As Texan Mac Man suggested, the breaking glass sound in most cases suggests bad memory. The startup chime is a good sign; this is telling you most of the hardware has checked out and has initialized. After the chime, the powerbook runs a memory test...this is when you hear the sound.

Question: Is the warning dialogue saying "A Problem Was Detected With RAM or Cache Memory" or just the RAM or just the cache memory? There is a remote possibly you have a failed backside L2 cache memory but since you get the breaking glass sound, more than likely you have bad RAM or incompatible RAM or possibly a bad RAM slot.

Some Wallstreets are unable to install OSX with more than 256MB of memory present, but can then run the full 512MB of RAM once OSX is up and running.

I would try this: Since you are getting the warning dialogue about memory, you must have some version of "Classic" (OS 8.1 > 9.2.2) installed or on CD. When booted to Classic, see what the Apple System Profiler reports on the L2 cache.

Next, since a 256MB in the bottom slot still causes an install failure, do you have a working 128MB that you can try for the install?

Are you sure the Jag CDs are good?

Are you sure the HD is sound? You can boot to a Classic CD, launch the Drive Setup located in the Utilities folder on the CD, highlight your HD's name, then initialize as MacOS Extended Format (HFS+) while also running 'zero all data'. This will thoroughly clean the HD and spare/reallocate any bad blocks. Follow this with Drive Setup's Test Disk. Details can be found in Drive Setup's Help once Drive Setup is open.

jpl-

I am having difficulty upgrading the memory on a Wallstreet series I (250 Mhz processor with 80 MHz memory bus).

Some of the readily available memories for this computer seem to be PC66 -- perfect for the Wallstreet series II (which slowed the memory bus down to 66 MHz). Others seem to have too many or too few chips on the SODIMM to allow a second 256 MB SODIMM in the other slot.

I seem to recall your describing of a group of Wallstreet PowerBooks that could NOT support 256 + 256 under Mac OS X. Do I have that right? and if so, could you relate what group could not support the large memory configuration?

Hi Grant,

Possibly you are thinking of the Lombard with the troublesome CPU that cannot run any memory in the top slot with OSX (only a max of 256MB in the bottom) but can run 512MB (2x256) with 9.x.

From what I have read, I believe all Wallstreets can run 512MB without issue in both 9.x. and 10.x. However, there have been several posts over the years of Wallstreets flatly refusing to install and/or run OSX regardless of memory configuration. The usual fix is to replace the microprocessor card; I also vaguely remember that most of these cases were the Wallstreet Series I with the 83Mhz system bus.

If one has a RAM module that does not have the correct architecture for the Wallstreet, it will only recognize 128MB of a 256MB module. The Wallstreet's Grackle memory controller can address memory in banks no larger than 128MB; therefore the 256MB RAM module has to be built in a way that all 256MB of the memory chips are read.

Since you have the Series I, you would want PC100 RAM (which you recognize); you also want modules with 16 memory chips or 8 per side. OWC sells RAM specifically for the early iMac, Wallstreet, and Lombard.

Having said all this, I am not sure I have answered your question. If not, set me straight...
