<0> Similiar apprach, thanks markos_64
<1> When making a filesystem should I have a header (storing filenames, size, possition and that stuff) at fixed length and the rest of the disk for data?
<0> Read up on how other file systems work
<2> think, you havnt read much yet, filesystem have few file OR many (100's of thousands)
<1> Ok, I'll keep reading. But please tell me some basic info so I wont end up misunderstanding the text I read.
<3> in most filesystems, directory is like an ordinary file
<3> and so can be of any size
<3> the difference is that file is amorphous data, while directory contains some special structures
<3> so, i'd do it in two layers
<4> you can do filesystems any way you want
<4> its not easy and most of the work is in the design
<3> 1. design some way to store arbitrary-sized files on disk and grow/shrink them later, with files being identified by numeric id or something
<3> 2. design format of directory file, which will store, among others, the numeric id's of real files and subdirs. id of root directory can be stored directly in the first sector of disk.
<3> that's the way most unix fs's work, anyhow [with those id's called i-node numbers]
<5> do i have to remap every irq for itself , or are they remapped together
<3> they're remapped in bundles of 8
<3> do you have your PIC initialisation code now?
<5> yeah
<3> so you already have IRQs remapped
<5> i map irq0 to 0x20 and irq8 to 0x28
<3> good. so they're all set up.
<5> so irq1 is mapped to 0x21
<5> ?
<6> yes
<3> +
<5> ok i have setup a handler for interrupt 0x21 to catch the keyboard (it only prints a message), but if i press a key nothing happens
<5> if i do a "int $0x21" the handler responds
<3> did you do sti?
<3> also, did you enable IRQ1 in OCW1?
<5> doh i know that i missed something
<5> do i have to enable the irq explicit via ocw1?
<3> +
<3> IF takes precendence over OCW1
<3> to happen, both IF needs to be 1 and appropriate IRQ enabled in OCW1.
<7> !seen jetair
<7> hi, btw
<3> hi
<3> we have some sort of bot here?
<3> !seen foobar
<3> hm. nothing.
<2> one wonders what factoids a bot could be fed with we dont get a consistent stream of identical questions like ##php or #mysql
Return to
#asm
or
Go to some related
