Sorry for lack of response, I just needed to take a break as I have been trying to get this to work, only for running in to different set of trouble, when finally solved the first one.
I have flashed it with the latest bios, so that is in order.
Not tried with a bigger HDD after flashing I think.
Can't completely remember what I have done when, as I did a lot of testing in a short period of time.
I've tried every ram module I have, but none of them work, including the original, and some 32mb ones I used when it suddenly wouldn't boot any more.
I've taken all cards out, and also removed battery while disconnecting power cable. It makes no difference.
There are 2 types of beeps how ever, depending on ram module either 1-3-1, or 1-3-2 that is according to online sources identified it as a memory module problem.
Won't have much time to work on this for the next few days, but will try to figure what the problem is, now and then when I have a bit of time.
