Special Hardware Hints

20.1

The ISA bus implementation has the following four restrictions:

16 bit DMA cycles (located at DMA5 – DMA7) are not supported

An ISA device may take control of the bus (ISA bus master mode). This mode is not sup-

ported

Simultaneous usage of standard legacy floppy and DMA cycles is not possible

Using ISA graphic cards certain high color depth graphic modes may show disturbances

i.e. vertical lines. This is due to non optimum timings in the FINTEK ISA bridge which

cannot be fixed

20.2

The PCI bus implementation has the following three restrictions:

Only 3.3V PCI boards/cards are supported (do not use 5V PCI boards/cards without level-

shifter)

Only PCI boards/cards with speed of 33 MHz will be run

Some problems exists when using the KONTRON ADA9 Evaluation Board (refering to PCI

slots). KONTRON cannot guarantee that all PCI cards runs error-free

20.3

The standard version of AMD LX800 doesn't contain an EEPROM for storing a hidden key. Please contact

KONTRON for further information.
