====== 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**
</blockquote>
**RomWBW HBIOS v3.1.1-pre.21, 2020-07-03**

==== Boot CP/M ====

Type 'c' to boot CP/M:

**Loading CP/M 2.2…**

**CBIOS v3.1.1-pre.21 [WBW]**

**Configuring Drives…**

**A:=MD1:0\\

J:=IDE0:7**

**1590 Disk Buffer Bytes Free**

**CP/M-80 v2.2, 54.0K TPA**

==== 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.
