EPIA M VGA DRIVER DOWNLOAD

Customize The Tech Report Whilst getting corebootv2 going on your EPIA-M, you are almost certainly going to be re-programming the flash rom several times, and there is a very high probability that at one of these stages you will get a flash rom that fails to boot your mainboard into Linux. Like Ezra, Nehemiah is built using 0. You are not directly subscribed to this bug’s notifications. However corebootv2 has a few more tricks up its sleeve should you find yourself hungry for more. Here is a list of my findings:. The port is set up to use baud, 8bit, No parity, 1 stop bit.

Neutronbeam Zak, you know you can’t validate any of the above details without first throwing The DSDT describes the interrupt routing and power management capabilities of devices, and is what Linux uses for interrupt routing if it can.

In particular the interrupt processing in Linux can be done through ACPI, and crude power management support is provided. The other 64K is for your vga bios which is simply merged with the coreboot image. Otherwise you will end up with a very expensive paper weight as described earlier.

If you don’t, time to start capturing the output of the serial port and talking to the coreboot mailing list. I use ‘microcom’ which is simple and allows all output to be captured into a vva for later analysis. Decide which chip you are going to use for corebootv2, and which chip you are going to keep the original working bios in, and mark them clearly on this switch.

The credit can only be withdrawn by placing an order. If both are plugged in, the EPIA would display on the monitor.

There was an initramfstools bug that spia have caused this, but it should now be rectified. However it is easy enough to create your own using the steps above. Flash rom should search through a list of known flash rom device types until it finds the type of the original chip from your EPIA-M, and report what it has found. On freebios2, the i interrupt controller is never initialised, so it is understandable that if the vga bios has been playing with interrupts that after the STI intruction a random interupt vector is issued by the i – and hence the problems as reported.

The EPIA Ms also have control over the absolute picture position in software, though not with the horizontal and vertical scaling found on some TV output cards. LG HU85L projector needs but two inches to cast a 90″ picture. The configuration as set up by the buildtarget process will create a coreboot file which is exactly bytes long, which is exactly 64K bytes short of what needs to go into the K flash rom.

Make sure that you j compiled a kernel bzImage, and copied it to the file location you identified in the FILO Config file. July 21, The “Supra-Server”. Email me about changes to this bug report.

Having failed to understand the intricacies epla the pci detection and configuration mechanism, I have resorted to setting up the bridge manually, and with fixed memory resources, as annotated in the code. BIOS text is blurred and too bright – though still usable. The next problem encounterred was that after vga initialisation, the screen didn’t come on.

After groping around the XFree sources for the CLE I discovered a bios call to select which output device s to enable, and have added a call to that function to turn on the vag console. There are other areas which I consider n, in particular the setting up of the cardbus bridge. When installing ubuntu, I’m using the “standart” install, and when I’m prompted for grub location, I chose another place than the MBR, to keep Grub out of the startup process.

Hereafter, this howto refers to directory epua relative to these directories, unless an absolute pathlist is given. I’m using lilo because mandrake 10 was already installed on my computer, so I decided to keep its bootloader.

The new Nehemiah core carries forward Ezra’s 4-way associative 64KB L1 data and instruction caches, and its exclusive 64KB L2 cache with way associativity. Next you will have to run ‘buildtarget’ again to propagate the effects of the config change.

The next step is to create the build environment for the epia-m. If you need to make any changes to the configuration, for example you wish to locate filo.
