Title: Why bios(generic) is slow?

Well, IMHO, that's because, normal conventional BIOS do spend much of time in de-compressing its <<modules>>. as you can see those "modular BIOS" banner. load one module, decomp it, execute it, report module exit status and etc.. 256kb is not so vast space for even bios written in full .asm language. and some modules require the cpu to be in real 'real mode' some others run in something like flat mode. so there should be some resets also. hope it helps.   ----- Original Message ----- From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Sunday, December 29, 2002 7:21 PM Subject: Why bios(generic) is slow? Hi Can you tell me why generic bios is so slow compared to linuxbios. In other word, why linuxbios is fast? I think "do little thing" is not enough to explain x10 time difference. What does bios do other than linuxbios does and where it spend so much time? Regard, Heechul - HeeChul Yun,          Embedded S/W Team at ETRI phone: +82-42-860-1673
