I'm unfamiliar with the issue. Can you post the SeaBIOS debug output along with a description of the issue you are seeing? -Kevin

See the patch below as an example (100% untested). Hmm, I sent patches that did a similar thing but in a slightly more compact way.

Booting from USB cdrom device doesn't work

by Sven Schnelle

Hi List, i have seabios running on a Thinkpad T60 with coreboot and seabios as Payload. When trying to boot from a USB cdrom, i get the following errors: Booting from DVD/CD... wait_td error - status=184007ff uhci_send_bulk failed USB transmission failed wait_td error - status=184007ff uhci_send_bulk failed USB transmission failed WARNING - Timeout at wait_td:427! uhci_send_bulk failed USB transmission failed WARNING - Timeout at wait_td:427! uhci_send_bulk failed USB transmission failed read capacity failed atapi_is_ready returned -1 WARNING - Timeout at wait_td:427! uhci_send_bulk failed USB transmission failed Boot failed: Could not read from CDROM (code 0003) I have no knowledge about USB, so if anybody could help me in interpreting those messages, or has an other idea what the problem is, that would be great. Thanks, Sven

[PATCH] USB-MSC: Support multiple LUN devices

by Sven Schnelle

Add suport for using USB storage devices with multiple LUNs. One example for such a device is the HAGIWARA UDRW stick, which has one LUN that simulates a cdrom device, and one that acts like a disk device.

[PATCH] i8042_flush change

by John Baboval

When using seabios with Xen and qemu, I frequently get the following message: WARNING - Timeout at i8042_flush:69! I do have a slightly unusual configuration compared to the typical Xen configuration. We are running with no hvmloader. However I don't think that's related to this issue.... The flush routine attempts to read the queue depth's worth of data from the port and then checks to see if the queue is empty. There are two issues with this. First is that qemu and seabios disagree about the queue depth. Qemu's ps2 buffer has 256 entries, and I8042_BUFFER_SIZE is 16 for seabios. The second is that a command may arrive between the start of the flush loop and the completion. I believe a more robust way to do this would be to first issue a RESET command, and then flush. That resolves the issue that I am seeing.

Without this patch, LVT LINT1 is not configured by Windows guest because seabios MADT has no ACPI NMI structure which is used by Windows to setup LVT. So NMI interrupt would not be sent to CPUs when NMI signal happens on LINT1. But qemu/kvm inject-nmi feature had a bug that it sent NMI to CPUs without emulating LAPIC LVT. As a result, NMI interrupt is sent to all the CPUs even though LVT LINT1 is not configured. This is why inject-nmi behaves as if it works well on Windows guest. Regards, Kenji Kaneshige

[PATCH 0/2] allow loading of ACPI DSDT from qemu fw_cfg api

by Isaku Yamahata

This patch allows loading ACPI DSDT from qemu via fw_cfg interface. So this patch makes it easy for users to replace existing DSDT embed in seabios binary. Isaku Yamahata (2): util: add le32_to_cpu() seabios: acpi: allow qemu to load dsdt as external acpi table. src/acpi.c | 47 +++++++++++++++++++++++++++++++++++++++-------- src/util.h | 5 +++++ 2 files changed, 44 insertions(+), 8 deletions(-)
