The rest of the entry tells the firmware the starting sector and size of a disk image. It's mostly only used for obsolete junk (e.g. It's also very annoying (trying to squeeze anything good in 512 bytes is impossible). Note that this is inefficient because sectors on a CD are 2048 bytes but the BIOS will emulate 512 byte sectors, so every time you try to read a 512 byte sector the BIOS will actually read 2048 bytes and throw the "wrong" 75% of the data away. the first hard drive which would've been "device 0x80" will become "device 0x81" instead, etc). In this case the BIOS will create a fake "device 0x80" (from info in the BPB in the MBR) and mess up the device numbers for any real hard drives (e.g. The disk image should have an MBR with a BPB and partition/s, with an active partition pointing to where the operating system's boot loader is at the start of its partition. The boot loader can be any size you like (up to about 639 KiB) and the "device number" the BIOS tells you (in dl) will be for the CD drive itself, so you can load more stuff from the same disk using it. The rest of the entry tells the firmware the starting sector and size of a boot loader. for 80x86 it'll probably want the file \EFI\BOOT\BOOTX64.EFI). UEFI figures out which file it wants from the FAT file system based on converting the architecture into a file name (e.g. The rest of the entry tells the firmware the starting sector and size of a FAT file system image. ).įor 80x86 there are 4 different types of entries:
This is a list of entries with (up to) one entry for each kind of computer so that it's possible to create a single CD that works for 80x86 BIOS and 80x86 UEFI (and PowerPC and Sparc and.
It closes with AnyToISO: a conversion program that supports several files both in terms of output and input. But there is a big flaw: the Lite version (ie the free version) does not allow you to upload files over 870 MB. On the other hand you can integrate it with the shortcut menu on Windows, ie the one that opens by clicking the right mouse button on a file: a brilliant move, but does not save the whole situation.When a CD is being booted, the firmware checks the CD for a "boot catalogue" in the CD's meta-data.
Open ISO Converter is not the best free software to convert BIN to ISO on Windows, but it is nevertheless a program that knows how to be respected. The interface is quite spartan and rude, with few options, but this is not a flaw. You can upload the BIN file, set the output format, give it a name and start the conversion. But the above process is slightly different, because it forces you to add an “iat.exe” file that you need to unpack from an archive file attached to the software. Let’s say that it is simply an extra step.
The third option that we present today is AnyBurn: a very famous software in the field of burning, which includes a plethora of extra features. Also with regard to the conversion from BIN to ISO on Windows. It also supports other formats, such as CUE, DAA, NRG and DMG. And it is not at all complex, just like in other cases. To start, you have to click on the Convert button, select the source file, set the output and you’re done. Generally you will have to wait about 2 minutes for a 3 GB file. Even ISO Buddy is nothing short of excellent software. This program is highly recommended because it also supports large BIN files, and it is no coincidence that it is very similar to the software seen just above. Also because the conversion speed is more than good, and comparable to that of WinBin2Iso. In addition, the ISO Buddy interface is very easy and intuitive: not to mention the simplicity of the conversion operation, since you simply have to click on the Start Now button. In addition to this option, you will also find deletion and disc burning functions.
