How to handle AEP_CONFIG_DCB: Win98 storage?

NTFSD
1

Hi ALL,

I am writing a Port Driver to make my USB storage device visible as a normal
HDD.

When i receive AEP_CONFIG_DCB, how should I handle this?

Will I receive only one AEP_CONFIG_DCB per physical device ?

Currently I am filling in the geometrical information , Transfer length,
Device flags, Device Type, and the ISP intsert call down. is this enough ?!

Should i handle anything in Port driver that fills in the logical DCB
information?

How the IOS gets information about logical drives ?

TIA,

Anoop

Once IOS registers with configmgr, configmgr notifies IOS when it enumerates
each physical device. IOS, inturn, notifies its own clients (like yourself)
using AEP_CONFIG_DCB. This is where you insert yourself in the call down
stack. DISKTSD.VXD is the one that creates Logical DCBs for all recognized
partitions, floppy drives. CDTSD does the same thing for CD/DVD devices. The
USBLS120 sample should have enough information about filling in the DCBs.
