Re: Larger Disks in my 486DX2

You could use either a 27C or a 28C, as the pinout and reading signaling are the same. The only real difference will be with the programming, which you can do in your eeprom programmer. Nope, the pinout is different. Be careful! Please explain. In what way is it different, for a reading only …

@tiido, EzDrive removes 5kB from conventional memory of DOS in the form of limiting max conventional memory to 5kB smaller size. (I initially completely missed it, as it doesn't show as any running program) In my usecases, i mostly have many computers, where i go with the same CF card in a plug-and- …

konc, EzDrive does not render the CF card unreadable (OnTrack doesn't either, but installing/removing corrupts old data. EzDrive keeps old data in tact). And unless the ez.sys does not load for 286 (i currently don't have any 286 to test right now), it's going to take 0kB conv. memory, otherwise 5kB …

jheronimus, nice loot! I see the M321 board there! It's really nice board, having even a write-back cache support. (Need to populate the socket near cache chips) That VLB + EISA 486 board would also be really cool to get up and running. Do you mind writing down, what's written on the bios chip? Is …

bakemono, yes, EzDrive resides on bootsector on the disk. Super easy and goes together with the disk. (Perfect for CF cards) So as far as i understand, the XTIDE isn't worth it, when you already have an IDE HDD capable PC...

Why XTIDE bios is still a thing, when EzDrive seems to be so much easier? XTIDE is still a thing because as the name implies it's intended for... XT PCs. The XT BIOS does not include hard disk support like later systems, so you won't be able to use a hard disk without an external BIOS. As long as …

Playing around with my new chip cooker. XTIDE BIOS rom vs EzDrive DDO While messing around with that 386, i was able to get the original GTA working on it! (I have 387 co-processor as well) Though, it was about 2fps.

I've got myself a EEPROM programmer now and i'm trying out things that i wasn't able to before. This time i played around with the XTIDE bios on my 386 computer. I got it successfully working on 3C509B-COMBO card, but... First of all, it will take min. 1kB of conventional memory away. Additionally …

@Intel486dx33, this board is only 5V capable. I've tried both 486sx (2x25MHz) and 486dx2 (2x33MHz). Jumpers are correct, cache chips have been changed already numerous times. (And those chips do work on other boards) I don't think there's a connection problem... there's actually something wrong with …

Okay, some time has passed, but i got myself a chip burner and was able to test other bioses. Unfortunately the board isn't resurrected yet. The other bioses, i tried, were 25p2-j1; Soyo 486VESA (025P2) and Soyo 025N2, that have gone through this thread. I was also able to read the original bios off …
