|What's in the box?||The ZIP drive||PC Emulation||Change the ROMs||EtherLAN card|
|The PC emulation card is built around the 486 SX/40, you can use the image of a hard drive (up to 2GB) and use as mch RAM as your RiscPC can give to the application. |
You'll need some drivers to use it, they all can be found here:
PC Card Software
Here is the folder I get with all the software uncompressed. First, run Divacode to get a code!
|Then the installer located into the Release folder. Then, if needed, the patch for PCConfig before any utilisation.||Finally, you get this folder containing the software to emulate a PC. A good thing is to start with PCConfig to create your Drive C partition.|
|Then run MkBootDsc to create a boot disk with the requiered drivers for DOS/Windows. Keep the floppy inserted and run PC to boot with DOS.||This boot gives you access to the CD Rom as drive M:, then just type M:INSTALL to install Windows 95 for example, as I did it!|
|So, here is a configuration under Windows 95 with: |
On the right, everything works, video with sound!
I set the display in 16 bits, the same as the RiscPC to speed up the emulation!
|The RiscPC uses its own file system : the ADFS. ZIP disks formatted with ADFS can't be read under otheroperating systems. So, I wrote a little tool to read those files on an Atari.|
On the right, under RiscOs, I saved two files on my ZIP disk:
|My program READZIP |
Then I insert the ZIP disk into my Atari. My program shows the catalog of the disk in a simple manner, the two files are present with some infos for each.
Then, the program waits for a simple number (here 0 or 1) to know wich file to save on the Atari disk.
The program is written in FORTH with assembly routines to convert WORDS and LONGS from little endian to big endian, it accesses directly the sectors of the disk.
|The installed system; when I got the machine, was nor up to date, neither stable. ROMs were the RiscOS 3.70 but the system 4.02 was softloaded at boot time. The !BOOT folder wasn't organized as the other ones and it was always hard to adapt the advices from other Acorn users. |
Next, you can see the two components of the system 3.70.
|So, I acquiered the RiscOS 4.39 with its installation CD. This last is easy. First, you must swap the ROMs! Pulling them off requieres some patience as there is not a lot of room to insert something under the IC's. |
Once this is done, boot with DEL depressed to reinit the CMOS with the new organization as values have changed compared to the previous system.
|Then, you reach the desktop. You may have to modify some settings (screen resolution, CD...). |
Then, insert the CD and run the Install program. A new !Boot folder is created with the last functionnalities of the system 4.39.
There you are, just reboot and use it !
|The EtherLAN500 card lead to big problems as soon as it was inserted: |
The solution was to go to the command line (F12) and to type:
According to someone, those cards came from the educational world and were designed to use a network preventing the pupils from modifying the essential settings.
This card was kindly sent to me by John W. who took a lot of his time helping me to configure it..!
|This being done, I open the control pannel, select NETWORK and then INTERFACE. |
I select the EtherLAN500 card.
|Then, I clic on CONFIGURE and select the VIA DHCP protocol. That's all to use my LiveBOX from Orange.|
