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.
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.
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,
