Pismo 400 Issue

[Strimkind]

I was given a Pismo stock except the HD was smaller. After aquiring a fully loaded Wallstreet 14" with hinges not doing so well. I gutted it intended on making a good pismo out of it. After installing the HD and the RAM it refused to boot. I did not seat the CPU right so I reseated it and then got a hisssss and 3 beeps which stated no good ram banks...whatever than means. Bad RAM?

Either way, I pulled the RAM out and put it into my Lombard. Instant boot and recognized all 512MB of it.

Also, the Pismo needed to be plugged in for a while before it would even do anything. Any ideas? It did work before I started to play with it (after being plugged in for an hour).

Do the old "disconnect the PRAM battery", and reseat the CPU card - it goes in with a "thunk" sound.

I reseated the CPU to no go. I took the RAM out and put it into my Lombard along with a new 20GB HD, instant boot. Works great.

I installed the old Lombard RAM which apparently was running at half its capacity in the Lombard but full in the Pismo (128 and 256) but go figure the HD refuses to boot. Same went with the old Pismo HD I installed in the wallstreet. Very odd. I have decided I do not like Toshiba HDs as they are all the culprits.

Wallstreet and Lombard both have 66MHz system busses and can use PC66 SO-DIMMs. If someone went the cheap route on the Wallstreet and only used bare-minimum spec PC66 SDRAM (yes, Apple says you need PC100, but you really only need PC66 - the RAM operates at 66MHz), it may not work in the Pismo which really does require PC100. That seems like a plausible hypothesis for one of your problems to me. It's worth checking the specs on the RAM to learn what it is...

Peace,

I did not look at them that closely but that is a definite possibility. Either way, it was a benefit since the two ram chips originally in the Lombard were not suitable for the unit but work perfectly in the Pismo.

Now to tinker with the HD connection in the Pismo and get that drive booted...
