DOS Days

First International Computer (FIC)

FIC was a motherboard manufacturer for the IBM PC and its compatibles during the DOS era. They were especially prevalent during the Socket 3 through Socket 7 era, producing motherboards of good quality and flexibility.

The company started way back in 1979, and in more modern times has moved into automotive electronics and IoT solutions.

 

VIA4386-VIO

Year: 1993
Type: N/A
Form Factor: AT
Power Connector: AT
Chipset:VIA VT82C481/495
BIOS: Award BIOS v4.20
Slots: 6 x 16-bit ISA
Memory: 8 x 30-pin SIMM (max. 128 MB FPM)

This late 386DX motherboard is interesting. The board revision above appears to have a PQFP 386DX CPU soldered in, though the coprocessor socket clearly states it supports a 387 or 487 FPU. This tells us that the board can support a socketed 386 math coprocessor (the 80387) or the Intel 80487 chip which was released in 1991.

The Intel 80487 was more than just a math coprocessor for 486-era computers - it was a full 80486DX CPU with integrated math coprocessor, and can be considered the first chip-only (rather than full expansion card) Intel-branded upgrade for supporting 386 and 486SX motherboards. When used it would disable the existing CPU and bring the computer to the similar performance as a 80486DX computer.

The board also supports the Cyrix Cx486DLC.

The onboard cache can be configured from 64KB up to 256KB in eight 28-pin sockets plus one TAG RAM socket.

CPU support: 80386DX, Am386DX, 80486SX, 80486DX, or 80486DX2. This late 386DX motherboard also supports the Intel i487SX (A80487) upgrade chip. Clock speeds from 25 MHz up to 66 MHz.

The board allows for 64 KB up to 256 KB of Level 2 cache in eight 28-pin sockets plus two TAG RAM sockets.

486-GAC-V

Year: 1994
Type: Socket 3
Form Factor: LPX
Power Connector: AT
Chipset: VIA VT82C486A
Slots: 1 riser card slot
Memory: 4 x 72-pin SIMM (64 MB max.)

The GAC-V was a rare LPX-form factor motherboard (the one in the picture appears to be for an ICL (ICL-Fujitsu) PC, with parallel, serial, PS/2 keyboard & mouse, and video ports on the rear. Also on the board is an IDE and floppy disk controller.

The board is rather non-standard for 1994, with its two brown riser card slots (there are two because it supports VESA Local Bus), which implies it was to be used in a low-height desktop case, with expansion cards fitted horizontally into it. It has an embedded Cirrus Logic CL-GD5426 chip, a Super VGA VESA Local Bus graphics chip with 2 MB of video memory.

The board supports Front Side Bus speeds of 25, 33, 40 and 50 MHz. The Socket 3 supports 486SX, 486DX, 486DX/2 and 486DX/4 CPUs, and the L2 cache is configured as two banks supporting up to 256 KB.

Memory: 4 x 72-pin DRAM SIMM, 128 MB max.
BIOS: Award 4.51PG

Supports bus speeds of 50 or 66 MHz.
CPU clock speeds supported are 75 - 200 MHz.
This board also has the COAST (Cache On A STick) module slot (160-pin). 256 KB L2 cache onboard.

Supports Pentium classic up to 200 MHz, IBM 6x86 up to P166, or AMD K5 up to PR166. Pentium MMX is only supported with the use of a voltage regulator.

Redhill said this about the PA-2002: "A popular board for a while, forerunner of the excellent PA-2005, and one of the first half-decent non-Intel chipset mainboards for Socket 7, but not a board to love by any means: these were tricky to set up right and fussy about RAM and CPU matching, although perfectly practical once you got the hang of them. The PA-2002 was at its best with a Pentium and could be problematic with Cyrix or AMD CPUs in those early days. We preferred the then-current Chaintech 5IEM or QDI Explorer II for the 6x86. One unexpected bonus of the Apollo chipset, almost unique amongst Socket 7 boards, is that the memory management unit could address a single 72-pin SIMM module if required. This imposed a slight performance penalty, so it was usual to fit RAM in pairs.".

The PA-2002C board supports the Cyrix 6x86 CPUs from P120+ to P150+.

Supports bus speeds of 50 or 66 MHz. CPU clock speeds supported are 75-133 MHz (non-MMX). Revision A.1 is limited to a 66 MHz bus speed (jumper CLK3 is wired so it's not possible to set the bus at 75 MHz), but the final version (Apollo 585VP chipset) is certified to work at 75 MHz. With the 66MHz bus, the 1.5x clock multiplier is interpreted as 3.5x so you can also install Pentium MMX at 233MHz. Comes with 256 KB of Level 2 cache onboard.

CPUs Supported: Cyrix M1, AMD K5, Intel Pentium
CPU Clock Multipliers: 1.5x up to 3x.

VIA Apollo VP2 chipset, 1 MB L2 Cache (2 banks), 2 DIMM/ 4 SIMM slots, 3 ISA / 4 PCI slots, good jumper descriptions, up to 75 MHz bus speed (no 83 sadly!), Award BIOS. Performance is excellent, especially under Windows NT although system sometimes doesn't boot if cache timing is set at 2 clock leadoff cycle (2-1-1-1); strangely using the 6x86MX at 75 MHz bus speed, it worked pefectly and amazingly fast thanks to the linear burst feature. You may have to select 3 clocks (3-1-1-1) to undergo the booting sequence with the K6 and the Pentium MMX with some BIOS revisions. I regret I was not able to get the 512 kB version in time for some comparison. Its performance should be around the same in this case (3-1-1-1). If you are a speed freak and need a cacheable area over 64 MB, take into consideration the PA-2007, it's one of the fastest boards at the moment for all configurations.

 

Does not support AMD K6-2+ or K6-III+ CPUs due to the lack of a low enough voltage selection (3.2V, 2.9V and 2.8V only).

Here we have a VIA Apollo VPX chipset board in ATX format.

The K6 at 250 MHz was not identified correctly, but still worked fine. I had difficulties with the Pentium MMX 233. Sometimes it was detected as a Pentium MMX 133, but performance was good enough that I assume it was running at 233 MHz.

If you want to operate the motherboard at the fastest 83 MHz FSB, be aware you need the version with ICW W48C67-1 or ICS9147-01 clock generator - all others only support 75 MHz maximum. At 83 MHz bus speed, the SDRAM bank interleave had to be disabled, otherwise you will get lots of errors.

As with all VIA chipset-based boards, the PA-2010+ also supports the linear burst mode for Cyrix/IBM CPUs. With this you can expect performance gains of around 2-3%. If you are looking for an ATX board and VIA chipset, please consider the newer PA-2012 (1 MB) or the PA-2011 (with 512 kB) - they are much faster.

The PA-2010+ comes with 512 KB L2 cache onboard. External bus frequencies supported are 55, 60, 66, 75 and 83 MHz (the latter only possible with clock generator as described above). CPU core voltages supported are 3.2V, 2.9V and 2.8V only.

Known Revisions: 2.2

This is the ATX version of the PA-2007, but just with 512 KB of L2 cache. Technical facts are all the same.

Performance however, is not at the same high level as the PA-2007. The board has an additional connector for an AT power supply.

Our revision 2.2 does not have PCI special cycle support which the PA-2010+ has. The user gets into real trouble if he tries setting the SDRAM timing to 2/2 clocks. The result is that the board didn't want to talk with me until I made multiple use of the reset swich. I still haven't found out the reasons for this; it happened with every CPU and with EDOs instead of SDRAM, too. I'm confident a newer BIOS could improve this. I will also update this page as soon as I have some extra time to deal with this. Enable linear CPU burst when using Cyrix or IBM CPUs, you will be rewarded by a few per cents more performance. Be aware of using the Pentium MMX: This board is quite slow with it.

Supported bus frequencies: 50, 55, 60, 66, 75 MHz.
Core CPU voltages supported: 3.2V, 2.9V and 2.8V.

The FIC PA-2012 was the very first Socket 7 motherboard to support AGP.

Processors supported include the AMD K6 166 to 233 MHz, Intel P54CP55C, Cyrix 6x86 and M1 and M2. Clock multipliers of 1.5x, 2.0x, 2.5x and 3.0x are supported for P54C, 1x-4x for the Cyrix M1, and 2x up to 5.5x for the P55C, M2 and K6. Core voltage settings are 2.1V and 2.8V

Front Side Bus frequency settings are 55 MHz, 60 MHz, 66 MHz, and [on later board revisions] 75 MHz which drive the PCI bus at between 27.5 MHz to 37.5 MHz.

PA-2013

Type: Super 7
Form Factor: ATX
Chipset: VIA MVP3

BIOS: Award
Memory: 168-pin DIMM

The FIC PA-2013 came with either 512 KB or 1 MB of level 2 cache on the board. The 2MB of L2 cache starts off by enabling the VIA MVP3 chipset's 508MB cacheable memory area, up from the 254MB of the 1MB version and the 127MB of the 512KB version.

Like all newer MVP3 based motherboards, the PA-2013 ships from the factory with revision 'CE' of the chipset which eliminates the problems the chipset had with i740 based graphics accelerators.  The CE North Bridge is what drives the AGP 2X compliant port which is located just left of the chip itself.

This board does not support AMD K6-2+ or K6-III+ CPUs.

 

PA-2013 (2 MB cache)

Year: 1998
Type: Super 7
Form Factor: ATX
Chipset: VIA MVP3
Slots: 2 x ISA (16-bit), 1 xAGP, 4 x PCI
BIOS: Award
CPU Support: Pentium MMX, AMD K6-2, AMD K6-III, Cyrix MII
Memory: 168-pin DIMM

The FIC PA-2013 was a new generation of Super 7 motherboard, with support for AMD's K6-III processor. Since this CPU had its own L2 cache embedded on the CPU die, this bumped down the motherboard's "level 2" cache to be a "level 3" cache. The PA-2013 came with no less than 2 MB of this level 3 cache!

The board supports FSB speeds from 66 to 124 MHz, CPU clock multipliers from 1.5 - 5.5x, and CPU core voltages from 1.8V up to 3.5V in 0.1V increments.

The board also comes with two USB ports.

Like the original PA-2013, the 2MB version does come with Trend's ChipAway BIOS Virus Protection program that prevents boot sector viruses from loading even before your system starts up your operating system, just an added safety feature which may come in handy in this download-driven Internet world.

The PA-2013's performance rose an average of 3% in business applications, with performance increases peaking at the 5 - 7% level, placing it at the top of the Super7 motherboard performance charts.  As you might be able to guess, the improvements in 3D games is virtually un-noticeable, so if you have a PA-2013 or another Super7 board right now that you're happy with, there is no point to upgrading to this 2MB version simply because of the performance increases.  Even L2 cache dependent games such as Unreal didn't receive any improvement in performance as a result of the larger cache, in this case, their performance was being limited by the actual speed of the cache, not the size.

Memory support is via three 168-pin DIMM slots supporting EDO/SDRAM. Recommended RAM is PC100 SDRAM.

Now here's the real problem with that 2MB L2 cache, the board wasn't reliable enough at any overclocked FSB speeds (112MHz or 124MHz) most likely as a result of the quality of the L2 cache chips.  Where the older PA-2013's outfitted with 512KB or 1MB of L2 cache could perform quite reliably at 112MHz, the 2MB version couldn't, making overclocking on this board, other than with the 100MHz FSB, undesirable. 

A pretty good job as a board to stick a K6-3 on, but as for a K6-2 owner's overclocking wonder, the 2MB PA-2013 may end up being more of a disappointment.

This board has precisely the same layout as the PA-2007, the difference is the chipset. The PT-2007 is not suited for systems with more than 64 MB RAM due to the limitation of the cacheable area thanks to Intel's 430TX chipset. The BF2 jumper function has been integrated as well, but bus clocks over 66 MHz are not supported, FIC is strictly keeping the Intel specifications. I'm sorry I haven't had the time to try the remaining jumper setting possibilities, maybe 75 or even 83 MHz can be found. This will be updated as soon as I'll have time again to do this. Very hot: It's the second fastest board for the combination of Pentium MMX and Windows 95 and very fast with the K6 as well.

CPU support is broad: Intel, AMD and Cyrix processors are supported, and the Cyrix 6x86 MII Linear Burst Mode is available as a BIOS option. CPU voltage ranges are 2.0V up to 3.2V.

The VA-503+ supports FSB speeds of 60, 66, 75, 83, 95, 100, 112 and 124 MHz.

The board came with either a 512 KB or 1 MB L2 cache onboard with 5ns chips (necessary for MVP3-based boards to be stable at 100 MHz FSB or higher).

The AGP slot is AGP 2x, which is backward-compatible with AGP 1x.

A number of BIOS versions exist for the VA-503+. Those with 'JK' are designed for board revision 1.1A and those with 'JE' are designed for board revision 1.2A:
