ISA 8-Bit Ethernet Controller

ISA 8-Bit Ethernet Network Interface Controller

Introduction

ISA 8-Bit Ethernet Controller is an open source network interface controller (NIC) card, designed specifcally to be used in computers with 8-bit only ISA (aka XT) bus, such as IBM* PC, IBM* PC XT, various PC/XT compatibles, for example Micro 8088 system. It is based on Realtek RTL8019 ethernet controller and is NE2000-compatible.

Specifications

  • ISA 8-bit interface (62 pin / card edge)
  • NE2000 compatible
    • Note: Popular Crynwr NE2000 pocket driver does not support NE2000 in 8-bit slots. Please use a patched driver instead
  • Supports configuration using switches, jumperless configruaiton using RSET8019 utility or PnP
    • Uses DIP switches instead of jumpers for reliablity and ease of configuration
  • Boot ROM support
    • Socket supports 512 KiB Flash ROM, such as SST/Microchip 39SF040
    • Can be configured in 16 KiB, 32 KiB, 64 KiB, or page mode. In page mode the entire 512 KiB are accessible through a 16 KiB window
    • Also compatible with other DIP 32-pin Flash ROMs, such as 128 KiB 39SF010A, and 256 KiB 39SF020, or similar
    • 40-pin memory extension connector allows connecting up to 4 MiB of memory that can be used in page mode

ISA 8位以太网网络接口控制器

简介

ISA 8位以太网控制器是一种开放源代码的网络接口控制器(NIC)卡,专门设计用于只有8位ISA(又名XT)总线的计算机,如IBM*PC、IBM*PC XT、各种PC/XT兼容机,如Micro 8088系统。它基于Realtek RTL8019以太网控制器,与NE2000兼容

规范

  • ISA 8位接口(62针/卡边缘)
  • NE2000兼容注意:流行的Crynwr NE2000 pocket驱动程序不支持8位插槽中的NE2000。请改用补丁驱动程序。
  • 支持使用交换机进行配置,使用RSET8019实用程序或PnP的无跳线配置使用DIP开关而不是跳线以实现可靠性和易配置
  • 引导ROM支持插座支持512 KiB闪存ROM,如SST/微芯片39SF040可配置为16 KiB,32 KiB、64 KiB或页面模式。在页面模式下,可通过16 KiB窗口访问整个512 KiB,该窗口也与其他DIP 32针闪存ROM兼容,如128 KiB 39SF010A和256 KiB 39SF020,或类似的40针内存扩展连接器,允许连接最多4个MiB的内存,可在页面模式下使用,例如SST/Microchip 39SF040可以配置为16 KiB、32 KiB、64 KiB或页面模式。在页面模式下,可通过16 KiB窗口访问整个512 KiB,也可兼容其他DIP 32针闪存,如128 KiB 39SF010A和256 KiB 39SF020,或类似的40针内存扩展连接器允许连接最多4个MiB的内存,这些内存可以在页面模式下使用。用酒精清洁PCB。向SMD元件焊盘涂上液体助焊剂。焊接U1 RTL8019 IC。焊接R1-R7电阻器和RN1-RN4电阻器阵列。注意,RN1-RN3仅适用于如果使用DIP开关进行配置,则需要。无跳线配置不需要RN1-RN3。注意,RN1-RN3仅在使用DIP开关进行配置时才需要。无跳线配置不需要它们
