Detailed Procedure for K6-2+/3+ Upgrade
 

DELHI-III MOTHERBOARD UPGRADE PROCEDURE USING AMD K6+ CPUs
(Thanks to tjseven18; I added some details to his original description to provide a low-level type upgrade procedure you can implement step-by-step).

Here are the sequences I followed when I upgraded my system (under Windows 98).
(NOTE: SYSTEM CANNOT BOOT UNDER DOS WITH MILLENIUM EDITION)

A) Get the hardware components: AMD K6+ CPU, PC133/100 Memory, Thermal grease.

B) Get the software components: Go to <http://lightwaves.virtualave.net/k6cache/> and download the cacheonw.exe file to a floppy.

C) Record the original settings. With CyrixMII and PC66 memory, mine were:
SW1 / SW2 / SW3 / SW4 = On / Off / Off / On.
J15 = 2-3.
J2 / J9 / J3 / J4 / J5 = 1-2 / 1-2 / 1-2 / 2-3 / 1-2.
J11 / J12 / J13 = 1-2 / 2-3 / 1-2.

D) Check the speed of the original processor and original memory in the machine. Based on the above settings and using Sandra, I read CPU at 83MHz and memory at 55MHz.

E) Start the upgrade.
1. Install PC133 (or PC100) memory strips.
2. Change jumpers J16 / J17 to 1-2 / 2-3 respectively.
3. Using Sandra, verify that both the system and memory are running at 83Mhz.
4. Disable the External cache in BIOS (Reboot, and at “emachines”, press DEL key to enter the SETUP/Advanced menu, then disable the External Cache).
5. Save the BIOS change by clicking on “Save and Exit”, and let the system finish installing the operating system completely. At least, this verifies that you can still load Windows, but be very patient because it is extremely slow.
6. Shut down the computer (click Start/Shut down).

F) Say good bye to the old processor.
7. Remove old CyrixMII processor.
8. Change switches and jumpers respectively to:
SW1 / SW2 / SW3 / SW4 = Off / Off / Off / Off.
J15 = 2-3 (no change).
J2 / J9 / J3 / J4 / J5 = 1-2 / 2-3 / 1-2 / 1-2 / 1-2.
J11 / J12 / J13 = 1-2 / 2-3 / 2-3.
9. Install the new AMDK6+ processor.
 

G) Say hello to the new processor.
10. Fresh boot the computer.
11. At “emachines”, press F8 key to go to the option menu for DOS; then select the option “Command Prompt Only”.
12. When the C:> prompt is displayed in DOS, create a directory called “kcache”. You do this by typing “md kcache”, so the line with the prompt looks like C:>md kcache ; make sure you respect the space between d and k. Then hit Enter.
13. Insert the floppy in your drive and type the command to transfer the file to your C drive. The line should look like C:>copy a:\cacheonw.exe c:\kcache ; then hit Enter. Again, respect the spaces between y and a, then between e and c. The file should be copied.
14. When the DOS prompt reappear, type “win” so the line shows C:>win ;then hit Enter and let the machine install Windows (or at least that’s what I did). Be patient.

H) Activate the cache.
15. Restart your computer (click Start/Restart).
16. At “emachines”, press F8 key to go to the option menu for DOS; then select the option “Command Prompt Only”.
17. When the C:> prompt is displayed, type the command to activate the internal cache in the CPU, so the line looks like C:>c:\kcache\cacheonw.exe ; then hit Enter.
18. (I don’t remember if it is needed or not: If the C:> prompt returns, type “win” so the line shows C:>win ; then hit Enter).
19. Let the machine install Windows. Now it should be much faster. Do not stop the computer… there is one more thing to do.

I) Enable the automatic execution for the internal cache.
20. In Windows, click on the Start button and select Run from the pop up menu.
21. Type “sysedit” in the field (without “ ”); then hit Enter.
22. When the Autoexec.bat file appears, position the cursor at the very top left and hit Enter to add a blank line before the existing first line.
23. Type the following on the blank line C:\KCACHE\CACHEONW.EXE . This will automatically execute and turn the L2 on at boot.
24. …And guess what…

J) Be happy.
THE NEW CPU IS RUNNING !!! YOU DID IT !!! CONGRATULATIONS !!!

Please note that Sandra did not work well following the installation, but there are many other diagnostic systems that can provide the CPU and memory speeds. Good luck.

Memory Upgrades

"I have a etower 300k and I read somewhere that the Delhi III mobo in it only support 128mb memory modules and 256mb total. However, I have just installed a 256mb memory module and it seems to work fine. Now I am running with 320mb total ram (256+64). The module is a 256mb pc100 Kingston ValueRam. The other module is a 64mb generic pc133. I don't know if anyone else has this experience. By the way I have flashed the bios with the file found on the links, don't know if this has anything to do with it."

============================================================================

512MB ( 2x256) mb will work!
If not ....yes it will....and very well thank you! (either PC100 or PC133 low density)
I know some Delhi III mobos have proven to be limited but my Delhi III version loves it!

============================================================================

Mine topped out at 384MB

Installing ATI All-in-wonder 128 in E-300c (12/27/01)

<A>REMOVE PCI VIDEO CARD, and reboot using on-board AGP junk. At this point you'll need to replace that jumper for the onboard video to enable it.
<1>DOWNLOAD AND INSTALL LATEST VIA CHIPSET DRIVERS
<2>UNINSTALL ALL ATI DRIVERS using control panel add/remove programs, do not restart yet!
<3>DISABLE RAGE IIc AGP VIDEO in "my computer" / properties / device manager, click " disable this hardware profile "
<3b>SHUT DOWN, INSTALL NEW PCI CARD, CONNECT VGA CABLE to PCI CARD
<4>REBOOT TO BIOS SETUP, obviously make sure to set primary display to PCI, save changes and exit. If you see the machine detecting, and installing drivers for RAGE IIc, just click OK, don't worry. It should at this point also detect the All-in-wonder card and prompt you for drivers, so install those, and follow the rest of the directions as shown...
<5>ENJOY!

BIOS Upgrade

I successfully flashed the Bios to version 1.20 using E120.EXE. APM does not work under Linux and I was hoping the new Bios would fix the problem, it didn't. Apparently Trigem uses some nonstandard version of APM. There is code in the current version of the Linux kernel that disables APM when it detects a Delhi-III motherboard (I tested Bios version 1.20 with a custom kernel that doesn't disable APM). See http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=39191 for the bug report that led to this. APM seems to work under Windows 98, however.
