Now that I have my IDE card passing all the preliminary tests, I am trying 
to install CP/M on the Compact Flash drive and get the system to boot.

 

*System:*

Compupro ZPU at 2 mhz.

IDE CF Card, version 2.0a

IMSAI SIO for console

Ram 17 with Eprom installed at ‘E000’

8 gb Kingston CF

 

Have read, and re-read all the articles I can on the site, and decided to 
use the method put together by David Fry found here.

 

http://s100computers.com/My%20System%20Pages/IDE%20Board/Z80%20CP_M%203.0%20build.pdf

 

Step 1 - I modified HLDRBIOS.ASM to support my Console device (IMSAI SIO)

 

Step 2 - I modified CHARIO3.ASM to support my Console device 

 

Step 3 - Assembled and built the CPMLDR.COM

 

Step 4 - Copied it to the CF at Sector 0

 

Step 5 - Assembled and built the CPM3.SYS and copied it to the CF at sector 
112

 

Step 6 - Moved sector 48 to sector 63 on the CF

 

I know the install is not complete, but at this point I wanted to see what 
a ‘Boot’ looked like from David’s MYIDEROM:


 *At boot I see displayed on the console and MYIDEROM reports this drive 
information:*

 

Cyl:      3C82               Heads:            010                 Sectors:  
0048

 

Then I choose ‘C’ for Boot CP/M and here is where I see a problem:

Notice the ‘LBA = 003C003C’.   Why is that value so high and incorrect?

 

Any suggestions to getting is completed?

 

Thanks in advance,

 

Thomas
