22. Special Hardware Hints

The PC/104 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 Floppy and DMA cycles is not possible

Using ISA graphic cards, certain high color depth graphic modes may show disturban-

ces i.e. vertical lines. This is due to non-optimum timings in the FINTEK ISA-Bridge,

which cannot be fixed.

The PC/104+ 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 PC/104+ Evaluation Board (re-

fering to PCI Slots). KONTRON can not guarantee that all PCI cards runs error-free

In case you encounter problems during file operations (i.e. copy procedure during Windows installation),

these can usually be fixed by decreasing the memory speed. Changing the modul is not necessary, since the

modules are working correctly with lower memory speeds.

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

Kontron for further information about the usage of the EEPROM-variation.
