How to use a 27C010 instead of 4 27C256?

[electropt]

Hi,

First of all I must say I'm new to all this eprom address, bank, nibble, etc...

I've read some datasheets of various makers of eproms in search of a clue on how to use a 27C010 eprom instead of 4 27C256.

The aplication is simple, to have a single chip, multi boot ROM and select the one I want with a rotary switch.

I thought of using the CE (chip enable) of 4 27C256 but have seen a much nicer single (bigger) eprom solution somewere.

Can anyone help me on this one?
Provide sone insight on the matter, or point some nice source of information?

Thanks in advance!

Best Regards,

Hugo
