Problem found:
1) The "load plib" part in pm_setup.asm is not able to load >64k plib, because the si have an initialize value.
2) if added -g option to compile plib, the plib will become very large and pm_setup is unable to load it. So i am fixing pm_setup.asm, to let it able to load a very load plib |

Bug fix:
1) In header.h, the data are stored in 0x20000, but this address is too low
because the bootimage is very large when passed -g option to g++. Now, i
moved the os data area to 0x40000, so i have 0x40000-0x8000+1 size for the
bootimage
Enhancement:
1) the bootloader is loading 215 sectors to 0x8000
2) removed the folder library\standard\fs\vfs because no needed
3) VFS layer is now using virtual function, and added g++ option -fno-rtti
to make it compilable |

Enhancement:
1) split the bootloader into two, now, the first bootloader (the bootsector)
will load 8 sectors to 0x6000 then jump to 0x6000, and the second bootloader
(2nd sector to 9th sector, located in memory 0x6000) will load 1000 sectors
to 0x8000 and jump to 0x8000. |

Fixed:
1) Function "unsigned int getPage(unsigned size)" is wrong, because when it
allocated a page, it will not set the corresponding element of freePageList
to 1
2) Function "unsigned int getPage(unsigned size)" is wrong, because it
always return the same address
Fixing:
1) Function kfree() is wrong, because we should set zero to the address that
the pointer pointed to, when we free it. |

Fixed:
1) The concept of kmalloc() is wrong before. If user malloc 10 bytes, you
have to give him 4096. If you don't do it. the virtual address will be
wrong, because virtual address is used to control the PD and PT. Example:
If i allocate 4 bytes and kernel *JUST* give me 4 byte, and my virtual
address is 0x200000. Then i allocate 4 bytes again, and kernel give me the
virtual address 0x200004. The address 0x200000 and 0x200004 has the same PD
and PT.
Working:
1) adding a command cat to pshell
2) fixing the fread() |

Fixed:
1) ls(buffer) function in pshell.cpp
2) moved the os data area to 0x90000. The reason i do this is because the bootimage is very large now, ~610 sectors. The bootloader will load the bootimage to 0x8000, if the os data area is too low, it will have undetermine values.
Working:
1) program loader |
