3.1.3 Selection of the EPROM Size
With the ISA and AT/ISA96 versions, there is a PLCC32 socket with EPROM
(IC6) on the interface.
The sizes 27C256 (32 kbytes x 8) and 27C512 (64 kbytes x 8) are supported.
The EPROM may have an access speed of max. 90 ns. The solder jumper JP35
defines the setting of the EPROM size:
EPROM type Solder strap on JP35
27C512 1 - 2
27C256 2 - 3
The PC/104 interface has a flash EPROM with 128 kbytes x 8.
3.1.4 Disable Toggle
With switch 8 of the DIP switch SW1 (terminal strip SW1 with the PC/104
version, ON = jumper plugged-in), the toggle of the memory architecture can be
disabled from the PC. Then the interface always runs in loader-mode after a
reset, i.e. the program is always started in the EPROM. In this mode, bank-
switching of the XDATA RAM is possible on the interface.

3.1.5 Setting Bus Access Cycles
With switch 6 of the DIP switch SW1 in ON-position (jumper board SW1 with the
PC/104 version, ON = jumper plugged in), the bus can be set with 0 wait states.
If SW1-6 is set to OFF, the standard bus cycle is executed.
