Dear All:
The attached files are some demo program on the Protect Mode. I have added some new demo program and maybe help you for studing Protect Mode. The files list is belowing: Code: ;FileName :T10-3.ASM ;Function :None Privilege Switching in the TASK on Protect Mode ;FileName :T10-4.ASM ;Function :Demo call gates facilitate controlled transfers of program ; :control between different privilege levels. ;FileName :T10-5.ASM ;Function :Demo Task Switching and different Privilege Level Swiching ; :in the Task. ;FileName :T10-6.ASM ;Function :Demo Interrupt & Trap Handles on Protect Mode ;FileName :T10-7.ASM ;Function :Simulation Interrupt & Trap Handles on Protect Mode Last edited by Kevin_Zheng on 15 Sep 2003, 10:40; edited 1 time in total |

Dear All:
I have added two progarams on the package. It is belowing: :FileName :T10-8.ASM :Function :Demo Privileged Instructions :FileName :T10-9.ASM :Function :Demo I/O Protection and I/O Sensitivity Instructions In the future, I will adding some demo programs for page protection, V86 and PAE&PSE36 mode. I think that it maybe helpping you. And others, I hope that fasm supported belowing function: Code: ;The Trap Gates from 0 to 0CH repeat 12-0+1 DW ErrBegin DW ErrCode_Sel DB 0 DB AT386TGAT DW 0 end repeat ;The Trap Gate 0DH (#GP--General Protection Fault) Int0D Gate 0,GPTSS_Sel,0,ATTASKGAT,0 Because struct define doesn't support anonymous define, so I must use DB syntax on the repeat instruction. I understand why doesn't support it, because the struct define used the macro syntax, so the complier will not juge the anonymous struct and macro. So I recommend using "<>" on the struct define. It will solution the above question. It's used on masm/TASM for same as purpose. Last edited by Kevin_Zheng on 28 Sep 2003, 15:03; edited 1 time in total |

Please used the newest package. I have added one progaram on the package. It is belowing: Code: FileName :T10-11.ASM Function :Demo Interrupt and Exception Handling in Virtual-8086 Mode Notice : On the first the T10-11.exe must execute on the pure DOS eviroment.The maching state will changing V86 Mode, then executing [color=red]intff.com[/color] for return real mode. In the future, I will adding some demo programs for 4M&2M page protection, VME and PAE&PSE36 mode. I think that it maybe helpping you.
