Sorry for double posting.

You need 50pin SCSI cable.
Like this one: http://www.ebay.com.au/itm/24-50-Pin-SCSI3-Co … =item3f0f287607
Your HDD should work faster if you attach your Plextor separately.

There're LVD/SE 68pin connector and Ultra2 68pin connector. Try them both.

Try to restore the default SCSI BIOS settings. Then boot from Hiren's CD or something which has SCSI drivers into DOS, then try to restore default MBR running: fdisk /mbr and then reformat it: format c: /s.

Awesome setup, but it's a TX board... You should get rid of extra 64MB of RAM, it will do you no good. I would stick with a single stick of SDRAM if I was building a PC around TX. The cacheable RAM limit of 430TX is only 64MB, so everything above runs uncached and at horrible speed.

To learn more about 430TX limitations, visit this page: http://www.pcguide.com/ref/mbsys/chip/pop/g5iI430TX-c.html

Alternatively, you could get a K6-II+ or K6-III+ CPU with L2 cache built-in and forget about the limitation.

Thanks for the input. That page on the 430-TX chip set was very helpful

Dropped Ram down to one 64mb dimm

The SCSI dream is over for now: The Seagate Barracuda died and is now only appearing as a 1MB drive - Ill have to source another 68 pin drive or get an adapter/cable for the 80pin SCSI drive I have.

So I switched to IDE and removed the SCSI Host card.

The Awe 32 Is giving me nothing but trouble. No reported conflicts - all IRQ's ok - Weird stability issues within windows 95. Super slow booting - Long Pauses when loading - Low Volume - Crackling - Sometimes not even booting - Every time I shutdown getting stuck and not getting to the shutdown screen.

I had a spare Sound Blaster Live Value edition CT4670 so Im using that now and Windows 95 is operating as it should.

On closer inspection there is a solder like substance on the Awe 32 Capacitors. I have no idea if its leaking or it came from an external source.

Updated:

I've reverted back to the Awe 32.

Ive got the system stable however the Awe 32 is reacting strangely.

No conflicts reported. IRQ, DMA, all ok.

The sound effects are very distorted and crackled most of the time.
The music midi support sounds weird - instrument volumes seem weird, wrong notes, it sounds terrible.

However a minute ago doom started working perfectly with awe 32 music support but my sound effects disappeared.

What do you guys think of the capacitors in that picture?

Should I be allowing any dos drivers to run in the config.sys and autoexec.bat when Im running windows 95?

I have 2 CT3670 and both work fine. By the way, CT3670 is called Sound Blaster 32, it's not AWE 32. It's more like an early version of AWE 64 Value. An excellent ISA PnP sound card, I think 😀 Be careful with RAM slots, they're extra fragile.

The thing on the caps is most probably lead. This should not be the problem, as lead comes cold really fast as it drops and it would not damage the capacitors. At the same time, the liquid that's inside the capacitors is usually brownish/green/yellow, at least to my knowledge. The problem is elsewhere. Perhaps a good cleaning with soap and brush would reveal some damage?

A much more safer choice is the AMD K6-III. It runs at a higher voltage, but is not that picky about BIOS compatibility compared to the + versions. Performance wise they are the same (though the + can be overclocked much more).

Is it possible to use a K6-III chip on this board?
Doesn't the board require a 100mhz FSB?

Well, there's a page on a similar subject, http://www.thg.ru/howto/20000725/
Although I'm not sure if Intel boards have jumpers for over 66Mhz bus speeds.

testing out a K6-2 chip.

Its a K6-2 500 but I cant find the undocumented 83mhz bus speed on this P5T30-B4 rev 1.4 board.

Settings:

Multiplier x2 (6)
FSB 75mhz
CPU core 2.1v
IO 3.3v

Internal cache: enabled
External cache: enabled
System bios cachable: disabled

All else default in bios.

I get 450mhz and dos runs flawlessly.

Windows 95 C on the other hand crashes when loading with a protection fault.

Does windows 95 support the K6-2 chip? the date on the chip is 1998

This was a well-known bug back in the days. See here for the patch.

When you start your Windows 95-based or Windows 95 OEM Service Release- based computer that is using an AMD K6/2 (350MHz or faster), or an AMD Athlon (1.1GHz or faster), you may receive one of the following error messages:

Device IOS failed to initialize. Windows Protection Error. You must reboot your computer.
Windows Protection Error. You must reboot your computer.
While initializing device IOS: Windows protection error.

NOTE: This problem is very intermittent on the K6/2 at 350 MHz, but occurs more often at higher speeds. This problem can also occur when you start your computer in Safe mode.

worked flawlessly!

thanks 5u3!!

If the K6-2 is working, then the K6-III (regular version) should work as well. Getting this CPU means even more performance and because of the integrated cache it means you can say goodbye to the 64MB cache limit on the motherboard!

Im not sure about that. It looks like K6-3 chips core is 1.6volts

the motherboard does not seem to support that voltage.

but Im amazed at the speed of windows 95 with a K6-2 450.

Considering dropping back to the Intel 200 MMX 😀

K6-III+ chips are 1.6V (can be run at higher), K6-III is 2.4V, same as K6-2.
