Hi there,

In the meantime, I coded on my OS as well.
Well, here's version 0.1, you can't do anything useful with it.... ::)
You can download it at:

Please check it if it works for you

tried it on my laptop. Reports HD0 and HD1 and CPU@166MHz
after a short time, the screen blanks and the monitor looks to be turned off.

the last things it displays is "0" "16" on 2 separate lines...

laptop batteries are quite low, i'll try it again later ...

Ah, ok.
0 and 16 are some testings from mem_alloc and mem_free

fully-charged batteries didn't help. It looks like there's a "quota of interrupts" before the system gets wrong (pressing keys make it hang earlier)

Or maybe you're trying to set a video mode that isn't supported by my laptop. What should the OS do once those number have been written ?

Well, it doesn't change to any graphic mode, yet...
It should let you type something (for now).

Hmm, didn't have those problems, maybe I should make the keyboard buffer larger (since it only contains for one byte ;D )
anyway, thanks

is there any minimum amount of RAM you assume ? my laptop has only 48MB. Note that the problem also occurs if i don't touch any key (it only occurs later)

Could this come from some unexpected IRQ (real time clock or whatever) ? ...

No, I don't think so...
What are you specs (laptop) ?
I think it's a bit weird (for me).....
