I've got an old Pressario that I'd like to get up and running again. But I'm facing a rather serious problem - I can't interact with it!
It's a Compaq Pressario 7474
It starts ok, but it never get past the POST check. I tried to reset the CMOS, so now it shows the logo and checks the memory but does not go any further. Actually it doesn't check all memory, it stops short with 8 Mb left, but I guess that's occupied by videoRam for the integrated videochip.
I've tried with a different PSU, different RAM, with and without diskdrives connected, but it doesn't help.
I can't get in contact with the bios either (tried F1, F10, INS, DEL and any other key I could think of) and upgrading BIOS i a bit difficult as I cant get it to boot at all, not even from a disk.
