Older vintage Macs normally boot into 24-bit mode, which only allows access to 8 MB of RAM (exception: the LC and related models can see 10 MB). To go beyond that, you need to use the Memory control panel, set it to 32-bit mode, and reboot the machine.
BTW, if your SE/30 (and other vintage Macs with 68030 CPUs) has a dead PRAM, it will always power up to 24-bit mode after it's been shut off. In that case, set it to 32-bit mode and restart the computer. Dan Knight, LowEndMac.com On Mar 29, 5:39 pm, urquidez <[email protected]> wrote: > Hello all. Just upgraded from 8mb to 20mb.
