DIP / PLCC

[Niki Waibel]

hi,

it seems that more and more boards are using PLCC chips instead
of DIP chips.
(http://www.ioss.com.tw/web/English/RD1BIOSSavior/SelectionChart.html)

if DIP is used you can replace the onboard bios chip (normally
2mbit) by a 8mbyte (64mbit) (m-systems md-2800-d08 or md-2802-d08)
DIP chip. that way you have the possability to put the kernel and
a small rootfs directly into the bios chip.

why cannot you do this if your board uses a PLCC chip?
are there no PLCC chips with larger memory available?
what types of PLCC chips are used?
from which companies?
