Pentium 4 motherboard with 3 ISA slots with DMA support


It is hard to find a new Pentium 4 socket 478 motherboard with ISA slots. On
top of that, if you need DMA support, your task has become even more difficult.
There are a few here and there. We found one and are listing it here.

If you are wondering what DMA is, the following text will help.

A DMA controller can generate addresses and initiate memory read or write
cycles. It contains several registers that can be written and read by the CPU.
These include a memory address register, a byte count register, and one or more
control registers. The control registers specify the I/O port to use, the
direction of the transfer (reading from the I/O device or writing to the I/O
device), the transfer unit (byte at a time or word at a time), and the number of
bytes to transfer in one burst.

To carry out an input, output or memory-to-memory operation, the host processor
initializes the DMA controller with a count of the number of words to transfer,
and the memory address to use. The CPU then sends commands to a peripheral
device to initiate transfer of data. The DMA controller then provides addresses
and read/write control lines to the system memory. Each time a word of data is
ready to be transferred between the peripheral device and memory, the DMA
controller increments its internal address register until the full block of data
is transferred.

DMA transfers can either occur one word at a time, allowing the CPU to access
memory on alternate bus cycles-this is called cycle stealing since the DMA
controller and CPU contend for memory access. In burst mode DMA, the CPU can be
put on hold while the DMA transfer occurs and a full block of possibly hundreds
or thousands of words can be moved. Where memory cycles are much faster than
processor cycles, an interleaved DMA cycle is possible, where the DMA controller
uses memory while the CPU cannot.

In a bus mastering system, both the CPU and peripherals can be granted
control of the memory bus. Where a peripheral can become bus master, it can
directly write to system memory without involvement of the CPU, providing memory
address and control signals as required. Some measure must be provided to put
the processor into a hold condition so that bus contention does not occur.

ISA Motherboard

Legacy ISA Motherboards

Some people think that ISA motherboards are extinct. They should have been extinct as they were introduced in the 80’s. However; they have proved to be very resilient and are still in demand in certain industrial automation applications.

At, we sell motherboards with ISA slots from 1 to 14 ISA slots. Some are new and some refurbished. We also sell computers with ISA slots and motherboard + CPU + Memory kits with ISA slots. We call them specialty upgrade kits with ISA slots.

ISA Motherboards are needed by companies looking for compatibility with legacy technology that require an ISA motherboard with ISA slots. An ISA motherboard with ISA slots is an invaluable platform for companies with heavy investment in machinery that still requires controller cards / SBCs that run off an ISA slot.’s standard product line of ISA motherboard with ISA slot are available with one, two or three ISA slots. Whether your ISA card is full length or half length, we sure will have the right size ISA motherboard and chassis for you. Our ISA motherboard with ISA slots are compatible with a variety of older operating systems such as MS DOS, Windows 95, Windows 98, NT, 2000, XP etc.isa motherboard, pentium 4 motherboard with 3 isa slots,

The ISA bus is still used today for specialized industrial purposes. In 2008 a more modern ISA motherboard for Intel Core 2 Duo processors was released which in addition to other special I/O features, is equipped with two ISA slots. It is marketed to industrial and military users who have invested in expensive specialized ISA bus adaptor cards, which are not available in PCI bus versions. PC/104 bus, used in industrial and embedded applications, is a derivative of the ISA bus, utilizing the same signal lines with different connectors. The LPC bus has replaced the ISA bus as the connection to the legacy I/O devices on recent ISA motherboard; while physically quite different, LPC looks just like ISA to software, so that the peculiarities of ISA such as the 16 MB DMA limit (which corresponds to the full address space of the Intel 80286 CPU used in the original IBM AT) are likely to stick around for a while.

Many people think that computers with ISA slots will be either impossible to find or extremely expensive. At we use up-to-date industry standard components to custom-build computers with ISA slots that are very reasonably priced. We offer several versions of ISA motherboard with ISA slot. We work with you to design a system that is easy to use and highly efficient.

We carry motherboards in ATX, Micro ATX, AT and Baby AT form factor in socket 3, 5, 7, slot 1, II, socket A, 370, 478 and socket 775. In motherboard format, we have boards with 1 ISA, 2, 3 or 6 ISA slots. If you need more ISA slots than that, then we have to move you to a rackmount solution and there we can provide you up to a 14 ISA slot configuration.

Our trained sales staff will configure a solution of ISA Motherboard with ISA slot and related components to fit your needs. We work with major corporations, universities, small businesses and the U.S. government to develop custom designed computers using motherboards with ISA slots. We will do our best to help you keep your equipment humming.

Feel free to contact us with your requirements and we will be glad to configure an ISA solution for you.
