Q. Do I need any specific drivers off the DiskOnChip to be place on the IDE drive?
A. There are no drivers on the DiskOnChip which cannot be duplicated on the hard drive
by kernel compilation. So long as you compiled the kernel on the IDE drive with the
appropriate drivers for the SBC, you should be fine.
Q. Should I get these drivers off of the DiskOnChip and put them on my IDE driver just
in case?
A. "Drivers" are kernel modules, and are therefore kernel-specific, compiled at the same
time as the kernel. Unless your IDE drive uses the same kernel we use, the drivers off the
DiskOnChip will be useless. Whatever distribution you installed onto the IDE drive
should have provided drivers to match the kernel it installed on the drive. If you really,
really want to try the drivers from the DiskOnChip, then boot from the DoC and FTP the
modules to another machine.
The only drivers you'll need are rtl8139.o (for the ethernet) and soundcore.o (for the
sound). The OSS sound drivers will work if you also load sound.o and es1371.o, but
these two should not be loaded if you're using ALSA. To use ALSA, you'll just need to
use the modules (and libraries) that you've already compiled there on the IDE drive.
Everything else on that board is standard PC-compatible stuff and does not require any
special drivers to operate.
Q. We want to use the RAD as a mini terminal. How can we do that?
A. The RAD is just a serial device. You should have received a manual along with the
RAD, describing the operation and protocol of the device (I think it comes set to packet
mode by default). You just need to open a serial port and send/receive data...you can use
minicom (though you can't send control characters that way), or write a C program, or
even write a BASH script that uses echo and cat to write and read the serial port device.
Q. Doesn't the board already have device drivers for the RAD. I mean if I connect the
RAD to the serial port can I not send commands to the CPU?
A. No, the RAD just sends characters to the host PC's serial port when a RAD key is
pressed. What you do with the data is entirely up to you.
Q. Is there a small distribution of Linux (< 20 MB) that can support and run ALSA
without any problems?
