+====== Creating new CF disk for ZRC ======
+===== Introduction =====
+This page describe the process of creating a new CF disk from scratch for ZRC. There are multiple approaches and I have not decided on the final one. I'm documenting the current process. We start the process with a ZRC with a new CF disk.
+==== Load serial bootstrap ====
+After power is applied, there is a 3-second window when a serial bootstrap file can be sent to ZRC to be executed. [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=builderpages:plasmo:zrc:zrc_zrserloader.zip|ZRserld.bin]] is the file that should be send as a binary file. Once ZRserld.bin is received, it will run and display: **ZRC Loader v0.0** **Auto start at 0xB400**
+==== Load ZRCMon ====
+once loaded, ZRCMon will run automatically: **………………………………………………………………………………………………………………………………………………………….UX\\
+ZRC Monitor v0.7 7/24/20**
+==== Load ROMWBW ====
+==== Run ROMWBW ====
+Type 'g0000' to run ROMWBW
+<blockquote>
+**go to address: 0x0000 press Return to execute command hë**

+==== Initialize the first disk (C) ====
+Initialize disk C with “clrdir c:”, type 'Y' to execute the command
+==== Create file 'ROMWBW.IMG' ====
+Switch to drive C and use xmodem to create the file 'ROMWBW.IMG':
+“b:xm r romwbw.img” and pick 'RCZ80_zrc.rom' as the file to upload.
+==== Installation completed ====
+Once xmodem completed the loading of ROMWBW.IMG, the installation process is completed.
+===== TeraTerm macro =====
+The CF creation process can be automated with TeraTerm macro. Unzip and place the file in c:\TeraTerm\ZRC. The serial port is set to 115200 N-8-1 with RTS/CTS hardware handshake. Press reset and run the macro 'newZRCCF.ttl' within 3 seconds of releasing the reset button. It will take about 5 minutes to install.
