□ Regarding the functions unique to the X68000
|
||
|
|
RaSCSI is equipped with a virtual SCSI device called a bridge device,
|
||
|
|
You can bridge the host Raspberry Pi. With this bridge device
|
||
|
|
The following functions are provided by using the dedicated driver for X68000.
|
||
|
|
|
||
|
|
・Ethernet
|
||
|
|
It provides the same Ethernet function as Neptune-X. SCSI-connected Ethernet
|
||
|
|
RaSCSI behaves like a BOX. Relay packets to the Raspberry Pi TAP device
|
||
|
|
It is realized by doing. Similar to Ether+.
|
||
|
|
|
||
|
|
・Host file system
|
||
|
|
The emulator of X68000 provides a standard function equivalent to Windrv.
|
||
|
|
Mount the file system on the Raspberry Pi as a remote drive
|
||
|
|
I can.
|
||
|
|
|
||
|
|
□ How to activate the Bridge Device
|
||
|
|
If you set the keyword "BRIDGE" as the file name when RaSCSI starts up, it will be assigned to that ID.
|
||
|
|
Generate a Buzzilli device for it.
|
||
|
|
|
||
|
|
ex)
|
||
|
|
sudo rascsi -ID0 HDIMAGE0.HDS -ID6 BRIDGE
|
||
|
|
|
||
|
|
□ Dedicated driver
|
||
|
|
Two drivers are included in RASDRIVER.XDF or RASDRIVER.HDS included in the distribution
|
||
|
|
I am. It is better to mount RASDRIVER.HDS with RaSCSI and copy it appropriately to transfer to the actual device
|
||
|
|
It will be easy.
|
||
|
|
|
||
|
|
□ Ethernet connection
|
||
|
|
Ethernet driver (RASETHER.SYS) works with bridge device to connect to Ethernet
|
||
|
|
You can send and receive packets.
|
||
|
|
|
||
|
|
Below, the IP address of the virtual adapter (TAP) of Raspberry Pi is "192.168.68.1",
|
||
|
|
The case where the X68000 side is set to "192.168.68.3" will be explained.
|
||
|
|
|
||
|
|
-X68000 settings
|
||
|
|
RASETHER.SYS is made by modifying the driver for Neptune-X.
|
||
|
|
Exactly the same. In order to connect the X68000 to the internet, it is necessary to set other environment settings.
|
||
|
|
I will. Please check the setting method by yourself.
|
||
|
|
|
||
|
|
Below is an excerpt of CONFIG.SYS and AUTOEXEC.BAT that are actually used.
|
||
|
|
|
||
|
|
[Excerpt from CONFIG.SYS]
|
||
|
|
PROCESS = 3 10 10
|
||
|
|
DEVICE = \NETWORK\RASETHER.SYS
|
||
|
|
|
||
|
|
[Excerpt from AUTOEXEC.BAT]
|
||
|
|
SET SYSROOT=A:/NETWORK/
|
||
|
|
SET temp=A:\
|
||
|
|
SET tmp=A:\
|
||
|
|

|
・Raspberry Pi settings
|
||
|
|
I am using a TAP device, so please enable TAP. perhaps
|
||
|
|
If you're using Jessie these days, it should work from the beginning. The confirmation method is /dev/net/tun
|
||
|
|
If the file exists, it can be determined that it is valid.
|
||
|
|
|
||
|
|
The method of creating a virtual adapter is as follows.
|
||
|
|
|
||
|
|
[Set from /etc/rc.local etc.]
|
||
|
|
ip tuntap add ras0 mode tap user root
|
||
|
|
ip link set ras0 up
|
||
|
|
ifconfig ras0 inet 192.168.68.1/8 up
|
||
|
|
route add -net 192.168.68.0 netmask 255.255.255.0 dev ras0
|
||
|
|
|
||
|
|
By the above, communication between Raspberry Pi (192.168.68.1) and X68000 (192.168.68.3)
|
||
|
|
It will be possible.
|
||
|
|
|
||
|
|
When connecting to the Internet etc., bridge and routing on the Raspberry Pi side
|
||
|
|
Settings are required. Please set according to your environment. Wifi
|
||
|
|
In this case, there seem to be various problems in constructing a bridge.
|
||
|
|
NAT configuration is also recommended. The author uses it in rc.local with the following settings.
|
||
|
|
|
||
|
|
echo 1 >/proc/sys/net/ipv4/ip_forward
|
||
|
|
iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
|
||
|
|
|
||
|
|
□ Host file system cooperation
|
||
|
|
It provides the same functions as Windrv and WindrvXM that are often used in the X68000 emulator.
|
||
|
|
Raspberri Pi files if you include a dedicated device driver called RASDRV.SYS
|
||
|
|
It means that the system can be seen and operated as a drive on the X68000 side.
|
||
|
|
|
||
|
|
Registering a device driver is easy.
|
||
|
|
For example
|
||
|
|
|
||
|
|
DEVICE = \SYS\RASDRV.SYS
|
||
|
|
|
||
|
|
In this case, mount the root directory of Raspberry Pi by default.
|
||
|
|
The drive mounted when the device driver is started is displayed.
|
||
|
|
If you want to mount other than root, please specify the directory. /home/pi etc.
|
||
|
|
To mount
|
||
|
|
|
||
|
|
DEVICE = \SYS\RASDRV.SYS /home/pi
|
||
|
|
|
||
|
|
Specify. If you specify multiple directories, they will be mounted as separate drives.
|
||
|
|
It is possible.
|
||
|
|
|
||
|
|
If you are using SUSIE, please install RASDRV.SYS before SUSIE. When incorporated later
|
||
|
|
There are reports that it can not be recognized correctly.
