The '''Intel 8∕16 LAN Adapter''' is a 10Mbps network card. It is notable for being compatible with the IBM PC/XT because of its dual 8-bit / 16-bit operating modes. There are several revisions of the card which have different physical interfaces at the back. Revisions include: RJ45 + dsub15, BNC + dsub15, and possibly more.

</gallery>

== Boot ROM ==

This card's boot ROM socket takes a standard 32-pin EEPROM chip, as well as 28-pin EEPROM chips such as the 28C64. It has been tested extensively with the 28C64 chip flashed with XT-IDE BIOS images, both XT and AT versions. It is a reliable way to boot from a modern era hard drive connected to an XT or AT class system whose BIOS would not natively support it.

== DOS Support ==

The card's DOS drivers come with a configuration program (<tt>SOFTSET.EXE</tt>) that can be used to enable the ROM socket (it is disabled by default) and set the base address, as well as adjust all the usual options like the I/O address and IRQ. There is a configuration option to force 8-bit operation even while plugged into a 16-bit ISA slot. The packet driver for DOS works perfectly with the MTCP suite from FreeDOS.

Aquishix:

I think we should add a column for "linear speed scaling?" or something to that effect. There's a big difference between games whose speeds simply scale with the CPU speed vs. games that crash or manifest weird bugs when running on too quick of a system. -- aquishix on 2018-04-22 @ 6:22 UTC

List of CPU speed sensitive games

2018-04-22T06:21:12Z

Aquishix:

This is a list of games that do not run properly in some ways on CPUs faster than what was common than at the game's release. 1990+ for the most part, since before that, this was more often the case than not: As a general rule, games for IBM XT computers require a 8088 4.77 MHz to play right.

Some CPUs, for example AMD K6-2 and earlier Pentium IIs have selectable multipliers, which may help with achieving the lower speeds recommended for some of the games in this article. Additionally, disabling L1/L2 caches will slow down the processor as well, e.g. a Pentium III with disabled caches will be comparable to a 386. [http://www.vogons.org/viewtopic.php?t=38613 Setmul] is a software utility by forum member gerwin that allows multipliers and caches to be changed/disabled and enabled without a reboot. For certain P54C Pentiums, it also allows manipulating Test Register options for further speed control.

Also, it is possible to use a slow 3D card to slow some of the games down, especially with the early proprietary APIs; a special case here are Rendition Vérité cards, since their slow VGA performance will also bottleneck DOS games using these modes. Finally, as a last resort one may try slowdown utilities such as [http://www.cpukiller.com/ CPU Killer] and [http://www.hpaa.com/moslo/ Mo'Slo].

For games with unlisted CPU specs refer to the requirements published by the developers.

Aquishix:

This is a list of games that do not run properly in some ways on CPUs faster than what was common than at the game's release. 1990+ for the most part, since before that, this was more often the case than not: As a general rule, games for IBM XT computers require a 8088 4.77 MHz to play right.

Some CPUs, for example AMD K6-2 and earlier Pentium IIs have selectable multipliers, which may help with achieving the lower speeds recommended for some of the games in this article. Additionally, disabling L1/L2 caches will slow down the processor as well, e.g. a Pentium III with disabled caches will be comparable to a 386. [http://www.vogons.org/viewtopic.php?t=38613 Setmul] is a software utility by forum member gerwin that allows multipliers and caches to be changed/disabled and enabled without a reboot. For certain P54C Pentiums, it also allows manipulating Test Register options for further speed control.

Also, it is possible to use a slow 3D card to slow some of the games down, especially with the early proprietary APIs; a special case here are Rendition Vérité cards, since their slow VGA performance will also bottleneck DOS games using these modes. Finally, as a last resort one may try slowdown utilities such as [http://www.cpukiller.com/ CPU Killer] and [http://www.hpaa.com/moslo/ Mo'Slo].

For games with unlisted CPU specs refer to the requirements published by the developers.

List of CPU speed sensitive games

2018-04-22T04:40:16Z

Aquishix:

This is a list of games that do not run properly in some ways on CPUs faster than what was common than at the game's release. 1990+ for the most part, since before that, this was more often the case than not: As a general rule, games for IBM XT computers require a 8088 4.77 MHz to play right.

Some CPUs, for example AMD K6-2 and earlier Pentium IIs have selectable multipliers, which may help with achieving the lower speeds recommended for some of the games in this article. Additionally, disabling L1/L2 caches will slow down the processor as well, e.g. a Pentium III with disabled caches will be comparable to a 386. [http://www.vogons.org/viewtopic.php?t=38613 Setmul] is a software utility by forum member gerwin that allows multipliers and caches to be changed/disabled and enabled without a reboot. For certain P54C Pentiums, it also allows manipulating Test Register options for further speed control.

Also, it is possible to use a slow 3D card to slow some of the games down, especially with the early proprietary APIs; a special case here are Rendition Vérité cards, since their slow VGA performance will also bottleneck DOS games using these modes. Finally, as a last resort one may try slowdown utilities such as [http://www.cpukiller.com/ CPU Killer] and [http://www.hpaa.com/moslo/ Mo'Slo].

For games with unlisted CPU specs refer to the requirements published by the developers.
