This was my 2nd question - which exact software I should use to setup the clock and feed date/time to DOS on boot?

yea, I didn't do this one - will check this evening, thanks!

Another question - anybody tried 2 CFs on JR-IDE? One as Master and another one as Slave? I found dual adapters 2CF-to-IDE on Ebay and just curious if it's supported here...

I've never used the clock on the jrIDE ... the software is floating around with a link somewhere in the forums; I'll get that fixed so that it is in a more easily discovered location.

As for 2 CF cards, I wouldn't try that just yet. I'm looking to get some time to scrub the BIOS code and make sure nothing terrible happens. It's based on Hargle's original BIOS for the XT-IDE so there are some weak spots, like error handling.

Getting the BIOS fixed so that two devices work would be great. DOM as master and CF slave for file transfers and backing up the DOM. I use my Parallel port CF now, but it is slow and the driver software is rather large.

Oh, in "Related Files" on the left of the page - I didn't notice it right away :)

P.S. I found instructions how to use it: http://nerdlypleasures.blogspot.com/2014/03/ibm-pcjr-upgrades.html
The RTC is a Dallas 12887 module, and is socketed for replacement. The date and time is set by a program called rtc, loaded in the autoexec.bat file on startup. IRQ 1, 2 or 7 can be selected for its operation. I suggest IRQ2 because the parallel port uses IRQ7 and the keyboard on a regular PC uses IRQ1, which could possibly confuse some programs that are not PCjr-aware. The Speech Attachment also uses IRQ1.

In order to set the date and time, you will need a small program called rtc.com, available here:
http://www.retrotronics.org/svn/jride/t ... ebuilt/jr/

To set the date and time for the RTC, first, set the correct date and time in DOS using the DATE and TIME commands. Next, run the rtc.com program with the /r switch. This will send the date and time you told DOS to the RTC. Finally, add the rtc.com program to your autoexec.bat file with the /d switch. Upon every bootup, this will fetch the correct date and time from the RTC and automatically set it in DOS.

Two drives on the jrIDE works just fine. I did this not too long ago:
viewtopic.php?f=1&t=180&start=440#p1934

The BIOS has full support for two drives. The bug Mike is referring to is that it isn't correctly catching access to a 2nd drive when it doesn't exist, so in fact you're going to be LESS buggy if you run both drives at the same time. :)

Thanks! I thought something like that when I saw how jrIDE BIOS was hanging for a while on 2nd drive detection ;)

Boot takes 72 seconds from Power-Off and 48 seconds by Alt-Ctrl-Del :roll:
