-Supports 2.88 MB IBM PS/2 drives (e.g. IBM FRU 64F4148 and IBM FRU 64F0204), that require +5V on pin 3. This feature is enabled using jumper JP1.
b) Serial port.
-Uses UART IC in PLCC package, supports newer UART versions such as 16C650 and 16C750 with extended FIFO.
-Also compatible with 16550 and 16450 ICs in PLCC package.
-UART I/O address and interrupt is selectable using a DIP switch. Supported I/O addresses: 3F8h, 2F8h, 3E8h, 2E8h. Supported interrupts: IRQ3, IRQ4, IRQ5, IRQ7.
c) 8 KiB BIOS extension ROM.
-Supports 28C64 EEPROMs and 27C64 UV erasable EPROMs.
-The ROM is configured using a DIP switch: It can be enabled or disabled; the /WR line can be disabled; the address can be selected from 0C0000h to 0EE000h in 8 KiB increments.
All functions above are optional (can be either installed or not). They can be switched on or off.
