To help users diagnose boot errors, especially with external devices such as USB flash memory mass-storage, I've created this diagnostic MBR. It succinctly reports the values received from the BIOS, locates and reads the active partition boot sector, reports the magic bytes and and read-sector error code. Holding down a shift key during boot will force CHS mode even if LBA is detected.

The following series of patches add a work-around for a BIOS bug to the MBR code. The user can press a Ctrl key at boot-time to force the MBR to ignore the BIOS-reported drive number (passed in register DL) and use the first hard-disk device (0x80). This works around a common problem that otherwise results in the "Missing operating system" message. If the BIOS-defined boot device order

Version 2 of these patches includes optimisations suggested by H Peter Alvin to save bytes: * Use memory-mapped I/O register to read keyboard shift flags * Don't reload DX from memory; move immediate byte to register Tested using mbr.bin. TJ (3): mbr: Ctrl-key press forces load from first hard disk gptmbr: Ctrl-key press forces load from first hard disk isohdpfx: Ctrl-key press

Fix breakage in the "hide" option support patch: - The code which initialized the global variable "dapa" was lost in commit 81c203f2, therefore EBIOS access did not work properly. Fixed by removing the global variable completely and moving all bounce buffer handling into read_sector() and write_sector(). - write_sector() copied data to the bounce buffer, but then

This patches add support for dynamic sectors to GPT MBR code. First 3 patches are trick and optimizations to gain some space for the forth patch. I have a modified version of SeaBIOS, some code and some script o test it I'll send on a different mail.

Why insisting? Anyway appended is a dumper version. I could put up a binery version if needed. Let me know if so. -- MartinS /*

On additional note, I was able to use filler directories to circumvent the problem. This works for me since it is archives, but wouldn't for most. Here is an example: No filler files: ls -l - Returns no files Filler file at top of the directory structure (00_SAMBA) ls -l - Returns directories 0-D and N-Z Filler files the top of directory structure and where D's stoped (00_SAMBA and

Hi all, just a minor thing: Why does `doveadm proxy list` repeat the header line after each entry? Too me, that just makes the output harder to read. So instead of this: root at mail1 ~ # doveadm proxy list username proto src ip dest ip port info at domain1.de imap 80.152.196.98 222.133.127.53 993 username service src-ip dest-ip

HiI have a specific sample coming from a gamma(alpha,theta1) distribution and then divided into two parts first part follows a gamma(alpha,theta1) the second is gamma(alpha,theta2) then I would like to find the mle`s for theta1 and theta2 which I found. Now I would like to simulate those estimates 500 or 1000 times.I tried for loop but it did not work It wont do the loop the problem is that I need

Hi all, I use XP on my laptop PC, with 30 GB HD (single partition), and a 3.5" hard drive (not a stick), accessed through a USB encasing, partitioned as five logical drives. I have successfully set up syslinux to boot several Ubuntu versions from the primary USB hard drive partition, and no problems there. The problem is, I would like to have an entry in the menu, like "Boot from

I assume it should be possible to do a bit better than this. Is there an existing pass which "fills" delay slots or would I have to write one if I wanted slightly

Hello, I want to a select tag, where you can choose a number between 1 and 100. My inital code is based on the examples from Agile Web Development with Rails, and looks like this: view: <%= options = [["Select number of lines", ""]] + RfqLines::LINE_QTY select("rfq_line", "line_qty", options) %> model: LINE_QTY = select_fill def
