Господа, если кому нужен переходник с AGP на PCI, обращайтесь.
RUS, DDMA у него есть. Точно. Посмотри блок схему, которая чётко указывает какой контроллер реализует поддержку ISA.
Вот описание его возможностей:

The IT8888F/G is a PCI to ISA bridge single function device. The IT8888F/G serves as a bridge between the PCI bus and ISA bus. The IT8888F/G’s 32-bit PCI bus interface is compliant with PCI Specification V2.1 and supports both PCI Bus Master & Slave. The PCI interface supports both programmable positive and full subtractive decoding schemes.
The IT8888F/G also integrates two enhanced DMA Slave controllers for achieving PCI DMA cycles: PC/PCI DMASlave Controller & Distributed DMA Slave Controllers.
The device also contains one SM bus (single master mode) which can be connected to a Serial E2PROM for automatic power-on configuration. ITE’s proprietary (USA & Taiwan patent pending) power-on auto-configuration through SM bus can provide customer with maximum design flexibility. The IT8888F/G also implements the optional fast positive decode of F, E, D, C memory segments. This special feature can provide a direct connection to an FALSH boot ROM.
The NOGO function, which is also implemented in the IT8888F/G for enabling or disabling subtractive decode of PCI interface could be a software controlled output pin from other host controlled devices. The Serial IRQ is also implemented in the device for sending and receiving ISA IRQs & IOCHCK#. The device includes an ISA interface which supports full ISA compatible functions.
The IT8888G is available in 160-ball TFBGA package.
The IT8888F is available in 160-pin PQFP package.

Что касается i6300ESB, то он там нужен как раз для реализации PCI-X (3.3 вольта, 64 Бит, универсальный). Кстати, производитель честно использует шину CSA, к которой подключается гигабитная сеть.
Раз уж я взялся за дело, зацените что нашёл
Коллеги, прошу помочь в развитии этой темы. Я там обновил правила. Прочитайте, пожалуйста.
Думаю, здесь всё это есть.
Что думаешь?
