Need help...

[wrack]

Hi,

You might be thinking that I am crazy but here we go.

I have 3 PCs and all of them are loaded with different types of CD ROM and they all have different drivers.

One of them have 40X CD ROM and rest have 52X.

And I don't like to use generic driver if I a have a high speed drivers for those 2 CD ROM.

Now here is the question...

I want to make a bootable floppy in which there are two folders. One for slow CD and one for fast CD drivers in it. When I boot from floppy It should give me three options.

1. Boot with HIGH SPEED CD ROM support
2. Boot with SLOW SPEED CD ROM support
3. Boot without CD ROM support

Does any one knows how to do this...???

Will wait for reply...

ThX in advance...

firstly you have to ask yourself why you want to do this in the first place ??

secondly what OS are you running you could do it with a batch file and put a reference to the batch file in autoexec ??

more info needed and is there really that much difference in speed between 40 and 52, it is not as if the cd can even be read at that speed

Wouldn't have thought so. But had a weird problem the other day. CD which could be read by an 8 speed but not by a 40 speed.....guessing something to do with rotation...

Burnt a copy to fix problem, but am still somewhat confused as to why this happened? Any ideas Merlin....

yeah probably rotation speed and maybe something with the laser?

crazy yes I thnk you are. how do you know they have diferent drivers? win98 adn up will load default drivers which is good for anybodies use. I don't think you can tell the difference if they are fast drivers or slow ones. a driver is a driver. most of the time you need a driver is when you are in dos.

Now here is the question...

I want to make a bootable floppy in which there are two folders. One for slow CD and one for fast CD drivers in it. When I boot from floppy It should give me three options.

1. Boot with HIGH SPEED CD ROM support
2. Boot with SLOW SPEED CD ROM support
3. Boot without CD ROM support

yes that is possible but useless as they more than likely have the same driver.

take the win98 boot disk and open config.sys. now you will see a menu and in that menu you will see something like this

menuitem=CD, Start computer with CD-ROM support.
menuitem=NOCD, Start computer without CD-ROM support.

just change CD to FAST and add another one like SLOW

menuitem=SLOW, Start computer with slow CD-ROM support.

so now you ahve this

menuitem=FAST, Start computer with Fast CD-ROM support.
menuitem=SLOW, Start computer with Slow CD-ROM support.
menuitem=NOCD, Start computer without CD-ROM support.

now, you will see the label in the text below the menu. jsut chagne accordingly to teh drivers you want.

jsut a thought, but maybe the program on that cd was older than teh standard or was bad so the 40x couldn't read it as it was so fast.

generally most programs are written to be extracted at 8x anyway so a 56x cdrom will never run it full speed.

was the cd that you originally tried a burnt one or an original ??

personally i have never had any luck with generic 40x CD-ROMs they always seem to either die or have problems reading cds

but maybe the cd was being spun too fast or the laser on the 40x could do with a clean, but if the cd spins too fast it will actually begin to shake from side to side slightly and this will make it harder to read the cd.

hope this helps a bit

how do you explain the 56x then?

[zmerlinz]

what about the 56x ??

you said it was because it spun to fast, so why don't they have problems with any 56x speed, it spins faster then a 40x

[zmerlinz]

that is the thing, that the CD-ROM never actually spins the cd that fast not even 40x, you know when the are spinning fast because they make a hell of a lot of noise, you will sometimes get them spinning faster when you have a scratched cd, but now, they don't get the cd to spin that fast
