The battery is housed inside the ODIN (aka Dallas) real time cock (RTC). Refer this site for some tips on how to replace the battery: http://pc-restorer.com/replacing-cmos-batteries-in-old-pcs/

That is essentially the same I did. Made a copy of the disk and then ran Norton Utilities on it (since the original was unreadable under DOS and I didn't want to cause further problems). I think some of the files were corrupted, but it's fortunately not a crisis. But, as you've stated, once a disk …

Some older Sierra titles were speed sensitive and wouldn't initialise the sound card on faster systems. You could try the GoSierra patch. If you're running from MS-DOS mode, then you need to make sure that CTCM is loaded in your Config.sys file as a device driver. The DOS settings for the sound card …

No, it was definitely a 360k diskette. With the help of Norton Utilities, I was able to "reconstruct" some of the files on the disk. I've attached a zip file with the files that were on the disk. Initially, Norton Utilities just renamed every file as "FILE000X" and, by using the DOS editor, was able …

Nice board! I would also recommend to try some other floppy drives, had success with many old floppies that failed to be read in one. What is the exact size of the file? Is there any hint in the manual how to enable this feature by Software? I did try to read it another floppy drive, but no luck. …

This is the kind of board i use in my Turbo XT build. Quite speedy for an XT. I've been looking forever for the 10Mhz 8086 version but that one is extremely hard to find. The closest I got to an 8086 was to buy an old Olivetti M24 (AT&T 6300) that runs at 8 MHz. I believe that CPU can be upgraded …

Can these boards run at precisely 4.77 MHz? I've since packed away the motherboard as I'm wanting to build it into another case but, when I tested it, Landmark 2.0 & Norton SI 6.0 did indicate it was running at 1.0x that of a 4.77 MHz XT (in "de-turbo" mode). How "accurate" it runs at precisely the …

Thank you for the advice. I did try by cleaning my floppy drives (tried it with two floppy drives). I even tried cleaning the disk itself, but no luck. I'll try searching around for the Juko utilities.

If I can perhaps offer an alternative solution by asking the following question: Is there any particular reason why you would want to install both DOS 6.22 & Windows 9x on the same PC? Why not just install Windows 9x and set up a start up (boot) menu configuration on your PC? That way, you can …

Your only other alternative would then be to try and run your game via a Command Prompt from within Windows 9x. I can confirm that MPU401 redirection under Windows 98 seems to work on my system .
