3 Rechargeable AA's would equal 3.6v to 3.9v, probably a better idea than alkaline AA's which can be up to 1.7v each when new which would be over 5v for 3 of them.

You can get brand new cache chips from Aliexpress. You have to input the ic part number in their search engine. Make sure You buy from a reliable seller, there are some dodgy ones there, read the feedback, etc. Unless You have less than 256k cache, don't bother, most people reckon it won't make a …
Re: AWE64 and Duke 3D Problems
Posted on 2015-09-25, 05:16
Are You running it under Windows or DOS? By Dos I don't mean a win98 dos prompt but booting directly into Dos. What Awe64 setup lines are You using for Autoexec.bat and config.sys in Dos? I have a CT4520 and I think You can select Awe32 in Duke3d which would be the preferred option.

Have You reseated the cpu? A photo of the Motherboard would be nice, at least we can then possibly offer suggestions based on anything we might see.
Re: How to test 486 turbo? Or perhaps how to fix it?

The 1st 2 computer games I ever bought back in 1994 were Wing Commander and X-wing. I successfully completed Wing commander with the Turbo off on my 486 dx2-66 machine. I actually made it a mission to complete it as I was upgrading to a Pentium 133 and knew Pentiums didn't have a Turbo switch.

The LED wouldn't come on if the motherboard didn't register that the switch was pressed. What about any Turbo enable/disable in the Bios?

Run diagnose to make sure the memory checks out. I've got one Gold card with faulty memory. I have done that a couple of times, passed with flying colours. With respect to Your card with faulty Ram Phil, You can probably get a replacement via Aliexpress. Tricky replacing SMD parts, but doable with …

Thanks for the help Jolaes76. I tried everything You suggested but ERR014 Feedback path error persists. My Autoexec was the same, just with some lines further down or up the page. I did rearrange them accordingly to match the above post. I have found that adding Device=ctcm to config sys achieves …

I tried everything last night to get this working, but no go unfortunately. I renamed the install folder to "sb16" with all the main files installed there, as well as copying all drivers and sys files to "drv" sub-folder. The midi driver I renamed is the one for the awe card, not the sb16 card. I …

Assuming Your AWE64 Gold in PNP, make sure it has no IRQ or DMA conflicts with anything else You have installed. Make sure Your hdd settings are either set to the max for PIO and UDMA, or set to Auto. Also 32bit mode should be on. I don't have this mobo so don't know what options are available to be …
AWE64 value General Midi error "solved"

I have a CT4520 Value card that I got off Ebay recently, I think from a fellow Vogons member :) General Midi emulation does not work in DOS, as in using AWEUTIL /EM:GM results in an ERROR 14, Feedback path error message. According to the Aweutil txt file, it says a hardware compatibility issue, use …

Well, even with CT-479 + Pentium-M 7x0 you change 800 MHz FSB to 533 MHz FSB. Questionable decision. The only reason may be TDP/Fan noise... I used to run my Pentium M 740 at 216 x 13 for 2808mhz, that's over 800fsb I actually ran benchmarks comparing performance with a Pentium M 715 as well as the …

Thanks for the Vid Phil, enjoyed it a lot. I would suggest drilling a hole in the rear of the Case for the Turbo switch, it's not like Your going to be turning it on and off a lot. I was going to do a similar thing with my 486 mobo but ended up getting a Super socket 7 computer in an AT case for $20 …

I used Winxp 32bit and it worked fine. If You are using 64bit then it won't work. Download Hiren's boot cd and boot off of Mini Winxp if You need 32bit, then run the software from Your hdd. Hit F2 in modbin for more options, I only just discovered that.

I recently went through the same issue with an old 4.50G bios in my Lucky star motherboard. Try the version I have attached. EDIT. I just tried it with Your bios, works fine. Unless You are a serious bios hacker there doesn't appear to be too much You can adjust.
