* memdisk: Calculate mBFT checksum laterShao Miller2010-03-301-14/+15
| | | | | | | We were calculating the mBFT checksum too early; dpt_ptr could change after checksumming, so we now do it after that possibility. Signed-off-by: Shao Miller <shao.miller@yrdsb.edu.on.ca>

* memdisk: MBR not recognized correctlyBodo Stroesser2010-03-301-1/+1
| | | | | | | | | | | | | This fixes a small inaccuracy in memdisk: get_disk_image_geometry() does not use MBR data to detect disk geometry, since it checks MBR signature at wrong offset. This normally does not cause problems, because memdisk guesses a reasonable value, if no MBR is found. Signed-off-by: Bodo Stroesser <bstroesser at ts.fujitsu.com> Signed-off-by: H.

* core: remove do_idle from pollcharH. Peter Anvin2010-03-304-1/+7
| | | | | | | | | Remove do_idle from pollchar; it is highly inappropriate while, for example, checking for a keypress during disk activity. Furthermore, make sure we reset the idle counter on events that indicate actual disk activity. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
* cpuid.c32: very simple low-level CPUID info CLI routineH. Peter Anvin2010-03-302-1/+62

* core: Workaround for Xen HVM HLT-in-real-mode bugH. Peter Anvin2010-03-302-2/+52
| | | | | | | | | | | Xen HVM when used with the "vmxassist" program crashes if HLT is executed in real mode. Detect a version of Xen old enough to support "vmxassist", and if it is found, then disable HLT.

* | | | | pxelinux: move the stack to avoid AMI BIOS bugH. Peter Anvin2010-02-123-8/+24
| |_|_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is apparently some AMI BIOSes which leave a BEV stack just below 7c00h, which means that they can't return from the PXE NBP. Thus, for PXELINUX, move the stack down a few kilobytes. This particularly refers to the "rouilj/ops12" system my private sysdump archive.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we specify a smaller image than the screen size, tile it across the screen rather than leaving a big black box. This may have to be made configurable. Also note that Syslinux currently does not handle the case of an image bleeding off the end of the screen. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
